When Mueller testified to Congress in July 2019, it was under subpoena and after months of delay. Under oath, the Godot of prosecutors became the Bartleby of witnesses: Mueller spoke with extreme reluctance, deflecting or declining to answer questions 155 times. He refused to answer basic inquiries about key players in his own probe, like whether he had wanted to interview Donald Trump Jr. He never discussed the Russian mafia, and none of the members of Congress would raise the topic.
