A federal judge in Washington is weighing whether to recuse herself from the prosecution of Greg Craig, a month before the former Obama White House counsel is set to stand trial on charges he misled the Justice Department about his past work for Ukraine.

U.S. District Judge Amy Berman Jackson has scheduled a Friday hearing with prosecutors and Craig’s defense lawyers, but she has given no public reason for the court meetup. The hearing comes only days after Craig’s defense lawyers told Jackson about evidence they might raise at trial that involves her former law firm, Trout Cacheris & Solomon.
