Federal Criminal Defense Lawyers California

Verified Content

Last Updated: November 6, 2025

A California federal criminal defense lawyer represents clients in complex legal battles within the federal criminal justice system – with potential outcomes like incarceration, financial ruin, and irreversible reputational damage.

Federal criminal cases in California are different from state charges in almost every way: they carry more severe consequences, involve more complex rules, and are pursued by well-resourced federal agencies.

Whether you’ve been indicted, targeted by a grand jury, or are under active investigation, now is the time to act. Federal agencies like the FBI, DEA, or IRS may already be building a case against you – and once they act, they want to move fast.

    When Does a Crime Become a Federal Offense in California?

    The Tenth Amendment of the U.S. Constitution reserves most criminal enforcement to individual states. That’s why crimes such as DUI, assault, or theft are usually tried in state court.

    But when a crime affects national interests, crosses state lines, or involves federal property or agencies, it falls under the jurisdiction of the federal government.

    Your case may be prosecuted federally under the following conditions:

    • It violates a federal statute passed by Congress (like wire fraud or drug trafficking).
    • It involves multiple states or affects interstate commerce.
    • It happens on federal property (like property controlled by the federal government, including VA hospitals or administrative buildings).
    • It targets the federal government, its agencies, or its officials.
    • It involves serious, complex, or national-level criminal activity requiring federal-level enforcement and prosecution due to its scope or impact.

    Key takeaway:
    Being charged federally means more than just different prosecutors — it means facing a distinct legal framework with higher stakes. They fall under an entirely separate legal process than California’s state-level offenses. If you’re facing federal charges, you need a federal criminal defense lawyer in California who understands that system inside and out.

    Types of Federal Charges We Defend in California

    The federal system handles an array of serious offenses — from large-scale fraud schemes to trafficking cases that span jurisdictions. What unites all federal cases is the fact that the U.S. government prosecutes them aggressively, using its full legal and investigative power.

    At Combs Waterkotte, our federal criminal defense attorneys in California represent individuals facing charges like:

    • Federal drug trafficking and distribution
      Includes the manufacturing, sale, or transportation of controlled substances, especially when crossing state or national borders.
    • Federal wire fraud and federal mail fraud
      Using electronic communications or mail to defraud individuals or institutions – often charged in business or investment-related cases.
    • Federal money laundering
      Moving funds through multiple transactions or accounts to conceal the origin of illegally obtained money.
    • Federal tax evasion and financial crimes
      Occurs when individuals or businesses avoid paying federal taxes through deception or omission, often linked to broader fraud cases.
    • Federal weapons offenses
      Includes unlawful possession, trafficking, or use of firearms – especially by prohibited persons or in furtherance of a drug or violent crime.
    • Federal child exploitation and federal child pornography offenses
      Prosecuted aggressively in federal court, these cases require sensitive but strategic legal representation.
    • Federal cybercrimes
      Encompasses internet-based crimes that target individuals, businesses, or government systems across jurisdictions.
    • Federal public corruption and bribery
      Covers cases where officials are accused of abusing power for personal gain or financial benefit.
    • Immigration-related offenses
      May involve unlawful entry, visa fraud, or providing aid to noncitizens in violation of federal immigration law.

    To compare:
    State-level charges often involve routine police work and local courtrooms, while federal charges like wire fraud can draw intense scrutiny from federal agencies and a federal grand jury. The stakes – and the strategies – are entirely different.

    What to Expect in the Federal Criminal Process in California

    Facing federal charges isn’t like facing charges in state court. In many cases, investigations start well before an arrest is made.

    The federal prosecution process generally follows these steps:

    Step 1: Investigation

    Federal law enforcement investigations typically begin quietly and last for months. Agencies like the FBI, DEA, or IRS often track financial activity, gather electronic evidence, and build their case long before any charges are filed.

    Most common mistake: Delaying legal help until after you’ve been charged — rather than acting during the investigation. The earlier we’re involved, the more we can do to protect you.

    Step 2: Indictment

    If prosecutors believe they have enough evidence, they’ll present the case to a federal grand jury.

    If the grand jury agrees, it issues an indictment, which is a formal charge – often the first time a defendant learns they’re being prosecuted.

    Step 3: Arraignment and Pretrial Motions

    The defendant is required to appear before a federal judge and enter a formal plea. This is the first opportunity for your federal defense lawyer in California to weaken the government’s case and influence what happens next.

    In some cases, with pretrial investigation we can have the charges dismissed entirely.

    Step 4: Plea Negotiations or Trial

    While most federal charges result in plea deals, some must be fought at trial. We prepare every case as if it’s going to trial, and we’re ready to present your defense when that day comes.

    Trials in federal court demand sharp advocacy skills and an intimate knowledge of the Federal Rules of Evidence.

    Step 5: Sentencing (if applicable)

    Federal judges rely on detailed sentencing rules set by the Guidelines, considering both the harm done and your record.

    In some cases, mandatory minimums limit the judge’s discretion — increasing the stakes at sentencing.

    Step 6: Appeals (if applicable)

    A successful appeal requires an experienced advocate who understands how to spot legal errors and argue them in the appellate court system.

    In summary:
    The federal system is fast-moving and unforgiving in its structure. The government has already spent time preparing its case – and you deserve a federal criminal defense lawyer in California who will not back down from a fight, even against the might of the federal government.

    How Our California Federal Criminal Defense Lawyer Approach Federal Cases

    Federal defense isn’t just about statutes — it’s about knowing when to act, how to apply pressure, and how to navigate a system built for the prosecution.

    We focus on intervening early, investigating every angle, and building a relentless, client-first defense strategy.

    Step 1: Early Intervention

    It’s critical to involve a defense attorney as early as possible — ideally before charges are filed. If you’ve received a target letter, grand jury subpoena, or visit from federal agents, it likely means an indictment is being prepared.

    Our role starts with direct communication with the prosecution, asserting your rights, and helping shape the case before charges are finalized.

    Step 2: Strategic Investigation

    We don’t wait for prosecutors to define the facts. Using experts and seasoned investigators, we challenge the government’s narrative and uncover evidence that supports your defense.

    Step 3: Realistic Negotiation

    When the evidence is stacked and mandatory minimums loom, negotiating a favorable plea can prevent catastrophic sentencing.

    Our team balances plea negotiations with trial preparation, ensuring we don’t give up leverage while staying ready to go to court.

    You’ll get the facts, the risks, and the strategy — but the choice is always yours.

    Step 4: Trial Readiness

    When trial is necessary, we bring proven trial attorneys with a track record of federal victories to the table. We develop persuasive narratives, challenge government witnesses, and present your case clearly and forcefully to a federal jury.

    Step 5: Sentencing Advocacy

    A guilty verdict isn’t the end — we shift focus to minimizing the impact. Our team crafts persuasive sentencing arguments, emphasizing mitigating circumstances to secure the lowest sentence possible under — or outside — the Federal Sentencing Guidelines.
