The most important federal prosecutor seat on the East Coast — overseeing more than 300 attorneys and offices from Alexandria to Norfolk — is now being run on an interim basis by someone with virtually no experience litigating in federal court. This is a direct consequence of an obscure legal mechanism: the Federal Vacancies Reform Act, which limits how long an official can serve in an acting capacity without Senate confirmation. In November 2025, a federal judge ruled that Lindsey Halligan had exceeded the permitted timeframe while holding the prosecutor position without that confirmation, accusing her of 'impersonating' the role after she lost legal standing to do so. Halligan — Trump's former personal lawyer and someone with no prior prosecution experience — resigned in January following that ruling.
Notably, Halligan was not the first attempt to fail. Before her, Trump had nominated Erik Siebert for the position, but Trump himself then forced Siebert out. Between the two turnover periods, the prosecutor's office had to rely on an administrative assistant, Frank Bradsher, to temporarily manage daily operations. This string of failures occurred right after Halligan pursued — and lost — prosecutions against former FBI Director James Comey and New York Attorney General Letitia James, two highly political cases that consumed considerable office resources.
Now, Stamos steps into that void with a markedly different profile: a two-term prosecutor in Arlington who worked in the county prosecutor's office beginning in 1987, won election in 2011 to succeed Richard Trodden, then was defeated by fellow Democrat Parisa Dehghani-Tafti in the 2019 primary election — a race once described as expensive and contentious. Afterward, Stamos moved to the U.S. Department of Justice under Trump's first term, then held leadership positions in the office under Virginia Attorney General Jason Miyares — whom she once served as deputy before much of his staff lost their jobs after Miyares lost his reelection bid last November.
A federal judge once accused her predecessor of 'impersonating' the prosecutor role after she had lost legal standing to hold it.
Who Benefits, Who Risks
With experience primarily at the state and local level, Stamos has virtually no record of litigation in federal court — a notable weakness as she temporarily leads an office handling complex federal cases ranging from national security to large-scale financial fraud. The absence of a Senate-confirmed prosecutor for an extended period could slow major prosecution decisions while making the office vulnerable to entanglement in political disputes like the Comey and James cases.
The Bigger Picture
The upheaval in Eastern Virginia is not an isolated case. At the same time, the White House is also changing personnel in other important supervisory positions — Trump just announced his intention to nominate James M. McDonald, a former prosecutor who was part of the legal defense team representing Trump himself, to succeed the chair of the Securities and Exchange Commission (SEC). Meanwhile, the federal legal system is also facing pressure from multiple directions, as more than two dozen Democratic attorneys general and governors are suing the federal government over the suspension of SNAP benefits during the government shutdown — a sign that federal agencies, from prosecutors to social services, are operating under unstable conditions in terms of personnel and budgets.
What to Watch
The Eastern Virginia prosecutor seat still requires formal Senate confirmation, and the history of two recent failures suggests this process will be smooth sailing. At the local level, the competition between reform-minded and traditional-minded candidates — as seen with Josh Katcher challenging Dehghani-Tafti — shows that prosecutor politics in Northern Virginia remains volatile, and personnel outcomes at both the federal and local levels will continue to shape how criminal cases are handled in the region.
