The MSNBC host accused Republicans who have questioned the integrity of law enforcement agents of engaging in "tinfoil-hat conservatism."

"I think what we are seeing in our committee ... is an effort to attack the Department of Justice, an effort to attack the FBI, to attack [special counsel] Bob Mueller, is an effort to undermine the investigations and these institutions out of fear of what they’ll find and try to discredit them in advance," said Rep.
