An extraordinary standoff between the Justice Department and Manhattan U.S. Attorney Geoffrey S. Berman ended Saturday when the prosecutor agreed to leave his job with an assurance that his investigations into allies of President Donald Trump would not be disturbed.

The announcement capped two days of conflicting statements, allegations of political interference in prosecutions, and defiance from Berman. On Saturday, Attorney General William Barr said Berman’s refusal to resign under pressure prompted Trump to fire him. Trump tried to distance himself from the dispute, telling reporters the decision “was all up to the attorney general.”

This episode deepened tensions between the Justice Department and congressional Democrats, who have accused Barr of politicizing the agency and acting more like Trump’s personal lawyer than the country’s chief law enforcement officer. It also raised questions about ongoing investigations in the Southern District of New York, most notably a probe into Rudy Giuliani, the president’s personal attorney.

Barr set off the whirlwind chain of events on Friday night with a surprise announcement that Berman was resigning, without explanation. But Berman insisted he had not resigned, was not stepping down and his investigations would continue.

On Saturday morning, he showed up to work, telling reporters, “I’m just here to do my job.” Hours later, Barr announced Berman’s firing.  “Unfortunately, with your statement of last night, you have chosen public spectacle over public service,” Barr wrote in a letter released by the Justice Department. He said the idea that Berman had to continue on the job to safeguard investigations was “false.”

Although Barr said Trump had removed Berman, the president told reporters: “That’s all up to the attorney general. Attorney General Barr is working on that. That’s his department, not my department.” Trump added: “I wasn’t involved.”

The administration’s push to cast aside Berman amounted to a political and constitutional clash between the Justice Department and one of the nation’s top districts, which has tried major mob, financial crimes and terrorism cases over the years.
