The interim U.S. attorney for the Southern District of New York and two officials with the federal public integrity unit all quit after the Justice Department ordered the charges against Mayor Eric Adams to be dropped.

Danielle R. Sassoon, Manhattan’s interim U.S. attorney, built a life on conservative values and amassed a daunting resume. On Thursday, she took a stand against the Justice Department where she had made her career.

The vote moved Mr. Patel, a Trump loyalist, one step closer to leading the nation’s premier law enforcement agency.

Alan W. Filion, 18, of Lancaster, Calif., pleaded guilty to making false threats of mass violence, which prosecutors said prompted large police deployments and, in some cases, unnecessary detentions.

Federal prosecutors and securities regulators have gone after large companies for violations of the Foreign Corrupt Practices Act, which prohibits them from bribing foreign officials.

Mayor Eric Adams of New York gave a speech on Tuesday professing his innocence and saying that he would not put his personal interests above the city’s.

Eric Adams cultivated a close relationship with President Trump. Now, U.S. prosecutors in Manhattan have been told to drop the corruption case against the New York City mayor.

As the acting deputy attorney general, Emil Bove has overseen the forced transfers of senior officials and an effort to collect the names of F.B.I. agents who worked on Jan. 6 cases.

The department’s current No. 2 official, Emil Bove, escalated his growing conflict with the interim leadership of the F.B.I.

The prosecutor firings and a move to scrutinize thousands of F.B.I. agents were a powerful indication that the president has few qualms deploying federal law enforcement to punish perceived enemies.

The New York City mayor took a combative tone in a speech to clergy members after several days of absence from public appearances.

The list has generated unease inside the bureau given the mass firings at the Justice Department in recent days.

Senior officials under President Trump have talked with prosecutors in Manhattan about the possibility of abandoning the corruption case against New York City’s mayor.

The prospect of legal challenges to President Trump’s purges may be a feature, not a bug, for adherents of sweeping presidential authority.

The move follows the resignation of the department’s chief corruption prosecutor, who chose to step down after being told the Trump administration was reassigning him to a position related to immigration enforcement.

The number of arrests there was uncertain. Illinois officials, including the governor, said they had not been given advance notice.

The early days of the transition have been marked by dismissals and dread.

The White House defied a law that requires giving Congress 30 days’ notice and detailed reasons before removing the watchdog officials.

Ed Martin, a longtime advocate for Jan. 6 defendants recently named to run the prosecutors’ office, sought to undo a judge’s order barring Stewart Rhodes from visiting Washington.
