The audio, obtained exclusively by MSNBC, is of Nunes talking at a dinner event in Spokane, Washington, on July 30. He is asked by an audience member about the effort to impeach Rosenstein, which was only publicly supported by a small group of Republicans.
Nunes, who heads the House Intelligence Committee, seems to explain the main reason Congress hasn't taken up the issue is due to timing and the upcoming midterm elections.
"It's a bit complicated," he told the audience member. "We only have so many months left."
"So if we actually vote to impeach, OK, what that does is that triggers the Senate then has to take it up," he said, explaining that it could take away from other priorities of Congress.
