Hunting MS-13: Tucker Visits El Salvador, Talks to Assassin, Visits Prison

Mike Huckabee said Republicans must start acting like Republicans in Congress, taking issue with new criticism leveled against the party by Sen. Jeff Flake (R-Ariz.)

"The problem is you've got globalists like Jeff Flake who are in total disarray with conservatives," the former Arkansas governor told host Shannon Bream on Tuesday.

Flake wrote in his new book, "The Conscience of a Conservative," that Republicans are "in denial," largely supporting Trump on issues that go against long-held conservative principles.

"I've been sympathetic to this impulse to denial, as one doesn't ever want to believe that the government of the United States has been made dysfunctional at the highest levels, especially by the actions of one's own party," reads one line in Flake's book.

"If this was our Faustian bargain, then it was not worth it," Flake continues. "If ultimately our principles were so malleable as to no longer be principles, then what was the point of political victories in the first place?"

Flake specifically disagreed with the president's rejection of the Trans-Pacific Partnership trade deal, which he said goes against conservative principles of free trade and will "will haunt us for years."

Huckabee pushed back, saying that some congressmen know that "if they drain the swamp some of them are going to be drained with it."

"Conservatives want America to be strong," the former presidential candidate said. "They want to make sure that if there is free trade, which we do believe in, that it is fair trade and we're not getting sucker-punched by China and people in Europe and all over the world."
