ANDREA MITCHELL (HOST): Let me show you what happened on the House side at a hearing with [FBI Director] Chris Wray testifying yesterday when [Rep.] Louie Gohmert [(R-TX)] was questioning the FBI director about whether or not the FBI has been -- and Mueller -- are penetrated with people who are biased. 

[...]

MITCHELL: To some people old enough to remember the McCarthy hearings, that had a certain smell about it. 

SEN. BEN CARDIN (D-MD): Right, I agree with you, and there could be members of Congress that are going to do things that are, I think, crossed the line. But I think as an institution we will make sure that the Mueller investigation has the independence, has the resources it needs to bring its investigation to a conclusion. The American people will demand that, and we have to make sure that that, in fact, takes place. So I have confidence that we will protect the integrity of the Mueller camp investigation.
