“I can’t imagine that the special counsel is not going to release something that shows a roadmap for the House to investigate a conspiracy,” Sam Nunberg said Thursday.

"Correct, for articles of impeachment,” he said.

Nunberg later walked back the statement saying he expected the special counsel's office to give the House "a roadmap to their findings."

"I’m not saying that Mueller is going to say whether or not the president is going to be impeached," he said. "I don’t think he can.”

Rosenstein appointed Mueller in 2017 to investigate whether Russia interferred with the 2016 presidential election, including whether Russia colluded with the Trump campaign.

Trump has lashed out at Mueller, Rosenstein and the Justice Department many times. He frequently calls the investigation a "witch hunt."
