"It was not clear whether the attorney general's deliberations were influenced by Mr. Trump's refusal to concede his election loss or his fury over Mr. Barr's acknowledgment last week that the Justice Department uncovered no widespread voting fraud. In the ensuing days, the president refused to say whether he still had confidence in his attorney general," reports the Times.
According to one of the three anonymous sources, Barr had been considering an early departure since before last week, and that Trump's election fraud claims had not influenced his thinking. Another said that Barr felt he'd finished the job he set out to complete at the DOJ.
In addition to avoiding a confrontation with Trump over using the Justice Department to challenge the election results, Barr's departure would deprive the president of a cabinet officer "who has wielded the power of the Justice Department more deeply in service of a president's political agenda than any attorney general in a half-century," writes the Times, seemingly forgetting about Obama 'wingman' Eric Holder. Meanwhile, some Trump allies who have criticized Barr over inaction may be pleased by an early departure.
