Will Republicans Draw a Red Line for Trump?

First Read: “If things appear that the country is indeed headed toward a possible constitutional crisis — Trump instructing the Justice Department to fire Mueller, Trump pardoning aides and family members — there is a simple solution: Congressional Republicans can act.”

“They can do so by passing a law to reinstate Mueller, or they can threaten impeachment. The question, of course, is whether they’d follow through.”

“That’s why every member of Congress should be on the record on this question: What will you do if Trump tries to fire Mueller or pardon his aides or family members? And the fact that this question needs to be asked — six months into Trump’s tenure as president — is an extraordinary development.”
