MSNBC’s Andrea Mitchell tears into Devin Nunes for trying to undermine Adam Schiff

MSNBC's Andrea Mitchell on Friday trashed California Republican Congressman and former chair of the House Intelligence Committee Devin Nunes, saying that he had "discredited" the committee and that Republicans were over their skis in criticizing its new Democratic chair, Adam Schiff (D-CA).

"The personal attack on Adam Schiff" was an "attempt to completely undermine his authority over the intelligence committee," said Mitchell, with no small measure of disgust. "Seeing those House Republicans going after him yesterday led by Devin Nunes who completely discredited the committee, which had long been the Gold Standard of House investigating bipartisanship."

Mitchell then ran the widely-viewed clash between Schiff and his GOP colleagues, in which Schiff all but called them traitors, and sighed deeply.

"Well," she said, piling on a little more. "The Speaker of the House Nancy Pelosi today just tweeting, 'Adam Schiff's calm, professional leadership is something we should all be proud of, unlike his predecessor' -- she means Devin Nunes."
