The forcing out of Siebert because he refused to charge one of Trump’s political rivals marks an escalation in what the president’s critics have called a retribution campaign, with ongoing investigations also targeting Sen. Adam Schiff and Federal Reserve Governor Lisa Cook.

Trump has repeatedly accused James — who successfully brought a civil fraud case against him last year and leads multiple lawsuits challenging his administration’s policies — of targeting him for political reasons, calling her “biased and corrupt.”

James is “a horror show who ran on the basis that she was going to get Trump before she even knew anything about me,” Trump said during his civil fraud trial in 2023. “This has to do with election interference, plain and simple. We have a corrupt attorney general in this state.”

Following a three-month trial, a New York judge concluded that Trump and his family had committed a decade of business fraud by overstating the value of their properties to get favorable loan terms, fining Trump and his sons nearly half a billion dollars. An appeals court subsequently tossed the financial penalty but upheld the finding that Trump committed fraud.

A former police officer with Washington, D.C.’s Metropolitan Police Department, Siebert graduated from law school in 2009 and has worked as an assistant United States attorney in the Eastern District of Virginia since 2010. In addition to serving as a line prosecutor, Siebert headed the office’s organized drug crime task force and supervised the office’s Richmond division from 2019 to 2024.

Siebert began serving as the interim U.S. attorney on Jan. 21 after the late Jessica Aber, who ran the office from 2021-25, resigned following President Trump’s inauguration. Both of Virginia’s Democratic senators, Mark Warner and Tim Kaine, recommended Siebert to Trump in April, and Trump nominated him for the position in May.

“Mr. Siebert has dedicated his career to protecting public safety, from his work with the Washington, D.C., Metropolitan Police Department to his handling of violent crimes and firearms trafficking as a line Assistant U.S. Attorney in the Eastern District of Virginia. With his experience and dedication to service, Mr. Siebert is equipped to handle the challenges and important obligations associated with this position,” Warner and Kaine said in a statement in May, pledging to support his nomination.
