Fox hosts with close ties to President Donald Trump are denouncing Sen. Jeff Flake’s (R-AZ) legislative effort to protect special counsel Robert Mueller’s investigation into Russian interference in the 2016 presidential election, blasting the senator for insufficient loyalty to the president and claiming his bill is unnecessary because Trump has said he does not plan to curtail the probe.

Trump forced out Attorney General Jeff Sessions last Wednesday, replacing him with Matthew Whitaker, a Trump loyalist who had frequently criticized the Mueller investigation before joining the Justice Department. In response, a bipartisan group of senators tried to pass legislation to protect the probe yesterday, but they were blocked by Majority Leader Mitch McConnell (R-KY), who argued that the bill was unnecessary because Trump has said he does not intend to fire Mueller.

Flake, a co-sponsor of the bill, has said that he will not vote to advance judicial nominations in the closely divided Judiciary Committee or support them on the floor until the legislation receives a floor vote.

The president’s Fox propagandists responded with fury last night.

Trump confidant and Fox Business host Lou Dobbs argued that the “great president deserves the support of all Republican officeholders” and those pushing the Mueller bill are “separating themselves from his agenda and making, really, some rather silly and preposterous noises rather than standing tall and shoulder-to-shoulder with the president.”

Sean Hannity, a close adviser to the president who appeared at a Trump election rally last week, smeared “Sen. Jeff Snowflake” for having “again today exposed himself, well, not as a conservative.” The Fox News host condemned Flake for “threatening the president” in support of a bill that “supposedly protects Mueller from being fired by the president, which isn't happening,” and said that the senator “should be ashamed” for “blocking conservative judges, breaking a promise to the people you represent in Arizona.”

And Laura Ingraham, who was once considered for the post of White House press secretary, told her Fox News audience Flake was “trying to further harm his party before he leaves.” She asked Fox News contributor Andrew McCarthy about whether the bill is unconstitutional and discussed with former independent counsel Ken Starr the “young lawyers” whose confirmations will be put on hold due to Flake’s move. All three agreed that there is no real threat to the Mueller probe.

Since Mueller’s appointment in May 2017, Fox hosts including Dobbs, Hannity, and Ingraham have told their audiences night after night that his work is illegitimate and intended to damage the president and that it should be halted as soon as possible. Now that the president is taking steps to curtail the probe, they are doing everything they can to prevent any action to stop him.
