The Justice Department has filed a lawsuit against former White House aide Omarosa Manigault Newman for allegedly failing to file a required financial disclosure report after her 2017 firing.

The civil complaint alleges that the former “Apprentice” star “knowingly and willfully” failed to “file the required public financial disclosure report after her employment terminated with the Executive Office of the President.”

The suit claims that Manigault Newman was given a “post-government employment briefing” in December 2017, after her firing, in which “she was advised of her obligation … to file a termination financial disclosure report” within 30 days as part of the Ethics in Government Act.

Manigault Newman, who served as director of communications for the office of public liaison during her government tenure, allegedly ignored multiple email requests from the Justice Department, as well as the White House Counsel’s Office, reminding her to complete and return the requested documents.

A White House attorney had emailed the controversial reality star after the 30-day deadline had passed to warn that she might face a $200 late filing fee, but she continued to not respond to repeated efforts to get in touch with her.

The offense is punishable by a fine of $50,000, which the government is requesting the ex-White House staffer be charged.

The former Trump ally saw her relationship with the president go up in flames after she was fired by John Kelly and began releasing tapes of encounters she had with other Trump officials.

After her ouster, media reports began circulating that Manigault Newman had been physically dragged out of the White House after her contentious termination.

She denies those allegations, but that didn’t keep her from becoming a Trump target on social media.

In a statement, Manigault Newman’s lawyer John Phillips told The Post: “The White House chooses to abuse process and use the Department of Justice to carry out retaliation. The lawsuit alleges that Omarosa Manigault Newman ‘knowingly and willfully’ failed to file a report. This is untrue.”
