Barr’s comment comes just days after President Donald Trump said he was leaving the decision to his attorney general on whether Mueller could testify.
Trump has wavered publicly in recent days on the prospect of Mueller’s testimony before Congress as his administration has clashed sharply with lawmakers over demands for documents and testimony.
Judiciary Chairman Jerry Nadler, a New York Democrat, said last week the exact date for Mueller to come speak publicly before Congress is under discussion.
“It won’t be next week,” Nadler told reporters last Friday. “But we’re negotiating with him, we’re talking to him and the Justice Department.”
