Rep. Adam Schiff, D-Calif., on Sunday slammed the federal judge overseeing special counsel Robert Mueller’s case against former Trump campaign chairman Paul Manafort after the judge questioned how much money Mueller was spending as part of his investigation into Russian interference in the 2016 election.

“I’m not sure that it’s germane, for example, for the judge to be asking how much Bob Mueller has spent on the investigation,” Schiff said during an interview with CNN’s “State of the Union.”
