House Freedom Caucus Chairman Mark Meadows, R-N.C., said Monday evening he and a “number” of colleagues are prepared to make a move toward impeaching Deputy Attorney General Rod Rosenstein if he doesn’t submit to testimony under oath to explain reports that he spoke about undermining President Trump.

“We are pushing very hard to make sure that he comes in under oath to Congress and let the American people judge for themselves,” Meadows said on Fox News. “I can’t tell you that if he does not, there are a number of us that are standing by really with impeachment documents. That said, we cannot have this kind of activity continue at DOJ.”
