Former FBI Director James Comey is challenging the legality of President Donald Trump’s appointment of Lindsey Halligan as U.S. Attorney for the Eastern District of Virginia. Halligan, previously Trump’s personal attorney, was appointed last month and has since indicted both Comey and former CIA Director John Brennan. Comey’s legal team argues that her appointment is politically motivated and lacks legal validity, framing it as part of a broader effort by Trump to install loyalist prosecutors for political retaliation.

Comey, who pleaded not guilty last week to federal perjury charges related to his 2020 congressional testimony, is seeking to have the case dismissed. His legal filing also suggests that an “out-of-district judge” may be necessary to fairly assess the constitutionality of Halligan’s appointment, raising questions about judicial impartiality given the political backdrop.

The case is currently assigned to U.S. District Judge Michael Nachmanoff, a Biden appointee known for his professionalism and calm demeanor. Legal experts told CNN that Nachmanoff has a strong reputation for fairness and is not easily influenced by political pressure. He previously served as a magistrate judge and was confirmed to the federal bench in 2021 with bipartisan Senate support.

The White House defended Halligan’s role, with a spokesperson stating that President Trump has “full confidence” in her leadership. The spokesperson also called Comey’s legal challenge a “frivolous and desperate attempt” to distract from the charges brought against him by a grand jury in Washington, D.C.

Comey’s trial is expected to become one of the most closely watched legal proceedings of Trump’s second term. Observers say Judge Nachmanoff’s steady, apolitical approach will be crucial in navigating the intense public and political scrutiny surrounding the case.
