Federal Crimes We Defend

Our practice areas span the full spectrum of federal criminal defense. United States Attorneys aggressively pursue convictions across a wide range of federal criminal cases, and each carries severe penalties, including lengthy prison sentences, steep fines, and lifelong consequences. Whalen Law Office defends individuals accused of federal crimes across Texas, including in Dallas, Fort Worth, Plano, Austin, Houston, and other areas.

White Collar Crimes

White-collar offenses involve allegations of financial misconduct, often prosecuted under complex federal statutes. These cases frequently include charges such as:

• Fraud: Wire fraud, mail fraud, securities fraud, healthcare fraud, and mortgage fraud
• Embezzlement: Misappropriation of funds from businesses or government entities
• Insider Trading: Buying or selling securities based on non-public information
• Money Laundering: Moving illegally obtained funds through financial institutions to conceal their source

Federal agencies like the SEC, FBI, and IRS investigate these crimes extensively, making it essential to build a strong defense early.

Drug Offenses

Federal drug crimes carry some of the most severe penalties, especially when large quantities, firearms, or alleged conspiracies are involved. These charges often include:

• Drug Trafficking: Transporting controlled substances across state or national borders
• Drug Distribution: Selling or distributing illegal drugs
• Conspiracy: Allegations of involvement in drug-related operations, even without direct possession
• Manufacturing: Producing methamphetamine, fentanyl, or other controlled substances

The DEA and federal prosecutors aggressively pursue these cases, often seeking mandatory minimum sentences.

Violent Crimes

Some violent offenses fall under federal jurisdiction, especially when firearms, organized crime, or interstate activity are involved. These include:

• Weapons Charges: Illegal firearm possession, trafficking, or use of a firearm in a crime
• Robbery: Bank robbery, armed robbery, and carjacking with federal implications
• Kidnapping: Cases involving multiple states or victims under federal protection
• Homicide: Murder charges that involve federal law, such as killing a federal officer

Federal violent crime convictions often lead to life sentences or capital punishment, requiring a highly strategic defense.

Cybercrime and Computer Offenses

Computer crimes and technology-related offenses fall under federal law when they involve multiple states, government systems, or national security concerns. These cases include:

• Identity Theft: Stealing personal information for financial gain
• Computer Hacking: Unauthorized access to systems or networks
• Wire Fraud: Using electronic communications to commit fraud
• Child Exploitation Crimes: Online solicitation, possession, or distribution of illegal materials
• Computer Crimes: Unauthorized access to protected computers, data theft, ransomware, and cyberstalking under the Computer Fraud and Abuse Act (CFAA)

The FBI, Homeland Security, and the Department of Justice aggressively investigate and prosecute cybercrimes and computer crimes, often bringing charges under multiple federal statutes simultaneously.

Tax Crimes

The IRS and federal prosecutors take tax-related offenses seriously, with many resulting in felony charges. Common federal tax crimes include:

• Tax Evasion: Deliberately avoiding payment of owed taxes
• False Returns: Filing fraudulent tax documents
• Failure to File: Not filing required tax returns
• Employment Tax Fraud: Failing to pay payroll taxes or falsifying records

A strong defense can involve challenging the prosecution’s evidence, proving lack of intent, or negotiating for reduced penalties.

RICO and Organized Crime Charges

The Racketeer Influenced and Corrupt Organizations (RICO) Act allows federal prosecutors to charge individuals involved in alleged criminal enterprises. These cases often include:

• Drug Cartels: Large-scale trafficking operations
• Fraud Rings: Multi-state financial scams
• Extortion and Bribery: Organized efforts to gain money or power through illegal means

A conviction under RICO laws can lead to decades in federal prison. If you are facing these charges, contact our experienced RICO lawyers immediately!

Public Corruption

Government officials, contractors, and business executives may face federal charges for corruption-related offenses, including:

• Bribery: Offering or accepting money for political or business influence
• Embezzlement: Misuse of public funds
• Fraudulent Contracts: Deceptive business dealings involving government funds

Federal agencies thoroughly investigate public corruption cases, making an aggressive defense strategy essential.

Immigration Crimes

Federal immigration laws impose severe penalties for certain offenses, including:

• Illegal Reentry: Returning to the U.S. after deportation
• Visa Fraud: Using fraudulent documents to enter or remain in the country
• Human Smuggling: Transporting individuals across borders unlawfully

Immigration-related convictions can result in deportation, long prison sentences, and a permanent ban from reentering the U.S.

Federal charges can change the course of your life. Whalen Law Offices builds strategic, aggressive defenses against these serious accusations.

Grand Jury Subpoena & Target Letter Defense

The pre-charge stage is one of the most critical — and often overlooked — phases of any federal criminal case. If you have received a grand jury subpoena or a target letter from a United States Attorney’s office, you are already the focus of a federal criminal investigation. Acting immediately with experienced legal counsel is not optional — it is essential.

What Is a Target Letter?

A target letter is a formal notice from a United States Attorney informing you that you are a target of a federal grand jury investigation. Receiving a target letter means federal prosecutors believe they have substantial evidence connecting you to a crime. You are not yet charged, but an indictment may be imminent.

Many people make the mistake of contacting the U.S. Attorney’s office directly after receiving a target letter, hoping to explain their innocence. This almost always backfires. Federal agents are highly trained and will use anything you say to build their case. Our attorneys can communicate with federal prosecutors on your behalf, protect your Fifth Amendment rights, and  in some cases, prevent an indictment from ever being issued.

What Is a Grand Jury Subpoena?

A grand jury subpoena is a legal order requiring you to testify before a federal grand jury or to produce documents and records. Grand jury proceedings are conducted in secret: there is no judge present, no defense attorney permitted in the room, and the normal rules of evidence do not apply. Grand jurors hear only the prosecution’s side, which is why over 90% of federal grand juries return indictments when prosecutors seek one.

A grand jury subpoena can be directed at three types of individuals:

• Witnesses: People who may have relevant information but are not themselves under suspicion
• Subjects: People whose conduct falls within the scope of the investigation
• Targets: People for whom prosecutors have substantial evidence of criminal activity — the equivalent of receiving a target letter

Whether you receive a subpoena for documents or to testify, you have legal rights — including the right to assert your Fifth Amendment privilege against self-incrimination. Our lawyers will tell you how to respond, what documents to produce, what to object to, and how to protect yourself in a grand jury appearance.

Why Early Federal Defense Representation Matters

The period between receiving a target letter or grand jury subpoena and the return of an indictment is the single most important window in a federal case. During this time, our attorneys can:

• Communicate directly with United States Attorneys and federal investigators on your behalf
• Present exculpatory evidence that may persuade prosecutors not to seek an indictment
• Negotiate a favorable resolution before formal charges are filed
• Advise you on how to respond to document requests without waiving rights
• Assert and preserve your constitutional rights before any grand jury appearance

If you have received a target letter or grand jury subpoena in Texas, do not wait. Please contact Whalen Law Offices promptly for a confidential consultation.

The Federal Criminal Process

Federal cases move quickly, often leaving defendants feeling like they have no control over the situation. Our firm prepares clients for every stage of the federal criminal justice system, ensuring they know what to expect.

Investigation Stage

Federal agencies conduct lengthy investigations before bringing charges. Wiretaps, surveillance, and informants may be used to gather evidence. In many cases, individuals first learn they are under federal investigation when they receive a target letter from a United States Attorney’s office or when federal agents attempt to question them. Early intervention from a defense attorney can sometimes prevent an indictment altogether.

Grand Jury Proceedings

Unlike state cases, United States Attorneys present evidence to a grand jury, which decides whether to issue an indictment. Defendants rarely have the opportunity to defend themselves at this stage, making proactive legal representation critical. If you have received a grand jury subpoena, our attorneys will advise you on your rights and work to limit your exposure before any grand jury appearance.

Indictment

If a grand jury issues an indictment, formal charges are filed. At this point, a federal arrest warrant may be issued.

Arraignment

Defendants appear before a judge to hear the charges and enter a plea. This stage often determines bail conditions and other pre-trial matters.

Pre-Trial Motions

Defense attorneys challenge evidence, seek to suppress unlawfully obtained materials, and file motions that could weaken the prosecution’s case.

Trial

Federal trials involve strict rules of evidence, skilled United States Attorneys, and federal judges who expect well-prepared legal arguments. A strong defense requires a strategic approach tailored to the specific charges. Our trial attorneys bring extensive courtroom experience in federal courts across Texas, challenging the government’s case at every turn.

Sentencing

If convicted, federal sentencing guidelines influence the penalties. Judges often impose lengthy prison terms, but effective legal advocacy can reduce sentences or secure alternatives to incarceration.

Appeals

Defendants have the right to appeal a conviction, but strict deadlines apply. Filing a timely and persuasive appeal requires an attorney who understands federal appellate procedures. Our firm handles federal criminal appeals before the United States Court of Appeals for the Fifth Circuit.

Why Federal Cases Differ from State Cases

Federal criminal cases differ significantly from state cases in several ways:

• Prosecution Resources and Conviction Rates: The federal government devotes extensive resources to investigations, making these cases more challenging to defend. United States Attorneys have high conviction rates, making experienced legal representation essential.
• Federal Sentencing Guidelines: Federal judges rely on structured sentencing guidelines, which can lead to harsher penalties than state courts impose.
• Mandatory Minimum Sentences: Many federal crimes carry mandatory prison terms, leaving judges with little discretion. Strong legal defense strategies can help avoid these severe penalties.
• Differences in Evidence Rules and Procedures: Federal courts operate under different evidentiary rules than state courts. Understanding these nuances is essential for building a strong defense.
• The Scale of the Criminal Justice System: The federal criminal justice system is uniquely powerful—employing forensic accountants, surveillance specialists, data analysts, and experienced United States Attorneys who have often spent years building a single case. Defendants need equally experienced criminal defense attorneys who know the federal system from the inside.

Our Defense Strategy

Federal prosecutors build their cases using extensive investigations, surveillance, and cooperation from federal agencies. Defending against these charges requires a strategic, proactive approach. Whalen Law Offices fights aggressively at every stage to weaken the prosecution’s case and protect your rights.

Early Intervention During Investigation Phase

Federal investigations often last months or even years before charges are filed. Law enforcement agencies conduct surveillance, interview witnesses, and gather financial records, phone records, or digital communications. Many people learn they are under investigation when federal agents attempt to question them,  issue a target letter, serve subpoenas, or execute search warrants.

An attorney from our firm can intervene during this phase to prevent charges from being filed or influence the direction of the case. Contacting federal prosecutors early may allow for negotiations that lead to reduced charges or even a case dismissal. Speaking to investigators without legal representation puts you at risk—federal agents are trained to elicit statements that can later be used against you.

Thorough Case Analysis and Evidence Review

Federal criminal cases often rely on thousands of pages of documents, wiretap recordings, forensic reports, and witness testimony. Our legal team conducts a meticulous review of every piece of evidence, looking for inconsistencies, procedural violations, and constitutional rights violations.

• Illegal Searches and Seizures: If law enforcement obtained evidence without a proper warrant or violated Fourth Amendment protections, that evidence may be inadmissible in court.
• Unreliable Witness Testimony: Many federal cases rely on informants or cooperating witnesses who have incentives to testify in exchange for lighter sentences. Their credibility must be thoroughly examined.
• Weak or Circumstantial Evidence: Federal prosecutors often rely on financial records, digital communications, or indirect evidence to link defendants to alleged crimes. Identifying weaknesses in the prosecution’s case can help negotiate better outcomes.

Strategic Negotiations with Federal Prosecutors

United States Attorneys have significant discretion in how they handle cases. Negotiating with them requires skill, credibility, and an in-depth understanding of federal sentencing laws. Our firm aggressively seeks alternatives to harsh penalties, including:

• Pre-trial diversion programs for eligible first-time offenders
• Reduced charges that eliminate mandatory minimum sentences
• Plea agreements that limit sentencing exposure in exchange for specific terms
• Cooperation agreements and proffer sessions—negotiated carefully to protect your rights and minimize sentencing exposure

While every case is different, our goal is always to achieve the best possible outcome through negotiation or trial.

Motion Practice to Exclude Evidence

Filing pre-trial motions can weaken the prosecution’s case by challenging illegally obtained or unreliable evidence. Our firm frequently files motions to:

• Suppress unlawfully obtained evidence (such as statements made without Miranda warnings or evidence seized without a warrant)
• Exclude unreliable testimony from biased or incentivized witnesses
• Challenge forensic evidence that may not meet scientific standards

Strong pre-trial motions can result in reduced charges, dismissals, or a stronger position heading into trial.

Trial Preparation and Execution

Some federal criminal cases cannot be resolved through negotiation and must go to trial. Our trial attorneys bring extensive courtroom experience from federal cases throughout Texas’s four federal districts. A well-prepared defense requires the following:

• Jury selection strategies to ensure a fair and impartial panel
• Cross-examination of prosecution witnesses to expose inconsistencies and bias
• Presentation of defense evidence that contradicts the government’s claims
• Compelling arguments that challenge the prosecution’s case beyond a reasonable doubt

Federal prosecutors must prove guilt with strong evidence. A carefully crafted trial strategy can lead to acquittals or hung juries.

Sentencing Advocacy

Even after a conviction, strong legal advocacy can affect sentencing. Federal judges follow strict sentencing guidelines, but downward departures and mitigating arguments can reduce prison time. Our firm fights for:

• Alternative sentencing options such as probation or home confinement
• Reduced prison terms by highlighting mitigating factors
• Post-conviction relief such as sentence modifications or appeals

Federal sentencing is harsh, but an experienced attorney can argue for leniency and reduced penalties.

Federal Criminal Appeals in Texas

A federal conviction is not necessarily the end of your case. If you have been convicted in a United States District Court in Texas — whether in Dallas, Houston, Austin, or another federal courthouse — you have the right to appeal to the United States Court of Appeals for the Fifth Circuit. Federal criminal appeals are highly technical, time-sensitive, and require attorneys with deep knowledge of federal criminal law and appellate procedure.

Our attorneys handle federal criminal appeals on grounds including:

• Insufficient Evidence: Arguing that the evidence at trial was legally insufficient to support the conviction under the standard of review
• Ineffective Assistance of Counsel: Demonstrating that prior defense counsel’s errors were prejudicial to the outcome
• Constitutional Violations: Fourth Amendment search and seizure issues, Fifth Amendment self-incrimination violations, and Sixth Amendment right to counsel violations
• Sentencing Errors: Challenging improper application of the federal sentencing guidelines or mandatory minimum statutes
• Prosecutorial Misconduct: Addressing improper conduct by United States Attorneys that affected trial fairness
• Newly Discovered Evidence: Presenting evidence unavailable at trial that could change the outcome

Federal appeal deadlines are strict — typically 14 days from the entry of judgment. If you believe your conviction or sentence was in error, do not wait. Contact Whalen Law Office immediately. Our experienced trial attorneys and appellate counsel will review your case and advise you on the strongest path forward.

Federal Crimes FAQ

How long do federal cases take to resolve?

Federal cases can take months or even years, depending on the complexity and whether a trial is necessary. Some cases are resolved quickly through plea negotiations, while others go through lengthy litigation.

Will I have to serve a mandatory minimum sentence if convicted?

Some federal crimes carry mandatory minimum sentences, but an experienced defense attorney can fight for alternatives such as plea agreements, sentencing reductions, or dismissals.

Can federal charges be dropped before trial?

Yes, but only under specific circumstances. Prosecutors may drop charges if the evidence is weak, constitutional violations occur, or defense attorneys successfully negotiate dismissals.

Should I speak to federal agents if I’m under investigation?

No. Speaking to federal agents without legal counsel can harm your defense. Even innocent statements can be used against you. Contact an attorney before answering any questions.

What should I do if I’ve been indicted?

Call a federal defense lawyer immediately. An indictment means prosecutors believe they have enough evidence to convict. Early legal intervention is essential.

What should I do if I receive a target letter?

A target letter from a United States Attorney means you are the focus of a federal grand jury investigation. Do not contact the U.S. Attorney’s office on your own. Call Whalen Law Offices immediately. Representation during the investigation phase is your best opportunity to prevent an indictment from ever being filed.

What is a grand jury subpoena, and what should I do?

A grand jury subpoena requires you to testify or produce documents before a federal grand jury. You have legal rights, including the right to assert the Fifth Amendment. Contact our office before responding to any grand jury subpoena. Our attorneys will advise you on how to respond and protect your constitutional rights throughout the process.

How much does a federal criminal defense attorney cost in Texas?

Federal criminal defense fees vary based on the complexity of the charges, the number of defendants and co-conspirators, and whether the case proceeds to trial. Given that federal convictions frequently carry mandatory prison sentences of five, ten, or twenty years or more, experienced legal representation is one of the most important investments you will ever make. Contact us for a consultation and we will discuss your case and our fees with complete transparency.

What is the difference between a state criminal defense lawyer and a federal criminal defense attorney?

Not all criminal defense attorneys practice in federal court. Federal criminal law, federal court procedures, and federal sentencing guidelines are fundamentally different from state criminal law. You need a criminal defense lawyer with specific experience in the federal criminal justice system, including practice before United States District Courts and direct experience opposing United States Attorneys. Whalen Law Offices focuses on exactly this type of representation.
