Fox News host Tucker Carlson engaged in an intense back-and-forth exchange with Hillary Clinton former campaign adviser’s Richard Goodstein. During a segment on Monday night’s “Tucker Carlson Tonight,” they discussed the “double standard” that existed between how Clinton was treated and how former National Security Adviser Michael Flynn was treated.

Carlson also confronted Goodstein with the recent revelations that one of Mueller’s former staff members, who was removed after Mueller learned of his anti-Trump texts with a colleague, is facing a review for the part he played in the Clinton investigation.
