Alina Habba has finally stepped down as New Jersey’s lead federal prosecutor after a three-month court challenge found her appointment without Senate confirmation illegal.

The US Court of Appeals for the Third Circuit concurred with a lower court ruling that Habba, formerly Trump’s personal attorney, was gifted the position of acting US attorney through a “novel”—and unlawful—“series of legal and personnel moves.”

Habba announced her resignation as acting US attorney for the District of New Jersey in a social media post Monday afternoon to “protect the stability and integrity of the office.” Habba, who helped defend Trump in his New York civil fraud case and defamation trials, has no experience as a prosecutor.

“But do not mistake compliance for surrender,” Habba wrote, announcing that she would continue to serve the Department of Justice as Attorney General Pam Bondi’s “Senior Advisor” for US attorneys.
