Judge Emmet Sullivan started the second part of the proceedings by walking back some of his harshest comments.

"I made a statement about Mr. Flynn acting as a foreign agent in the White House," he said. Sullivan added that he realized that was incorrect.

Prosecutor Brandon Van Grack said the foreign lobbying Flynn did ended before the Trump administration began.

Sullivan also walked back his treason questions. "I'm not suggesting" Flynn committed treason, Sullivan now said.

"I was just trying to determine the benefit and the generosity of the government," he said. "Don't read too much into the questions I ask."

Van Grack said Mueller's team has "no concern" or no reason to think Flynn committed treason.
