A federal judge has ordered Trump loyalist Lindsey Halligan to explain herself — and fast.

Judge David J. Novak in Richmond, Virginia, gave the controversial prosecutor just a week to justify why she continues signing official court documents as the U.S. attorney for Eastern Virginia, despite being ruled unlawfully appointed, The New York Times reported Tuesday.

The order comes after another judge, Cameron McGowan Currie, determined the Justice Department violated the Constitution when it installed Halligan in the post. Novak's order marks the "most robust" pushback yet against Halligan's refusal to step aside.

Novak warned that Halligan's repeated signing of court papers could constitute "false or misleading statements," hinting at potential disciplinary action.
