Brit Hume reacted to emails that showed a Justice Department attorney involved in the Mueller probe appeared biased against President Trump's immigration decree.

Tucker Carlson reported that Andrew Weissmann sent an email to outgoing Acting Attorney General Sally Yates, praising her for refusing to enforce the first iteration of Trump's travel ban.

"I am so proud and in awe. Thank you so much. All my deepest respect," Weissmann's email read, according to Carlson.

He said Weissmann "despises Trump so much that he supports politically motivated bureaucratic defiance of the president."

Hume said the incident appears to put the probe's fairness into question.

"This cringingly... suck-up email... raises questions about impartiality," Hume said.

He added that he does not like special investigations or special prosecution because, by setup, they appear to "create a bias in favor of action."

Hume said that the travel ban is an executive order issued by the president, meaning he has legal standing to make such a decree.

He noted that the Supreme Court appears to also believe he has the legal right to take such action.
