Sen. Bob Corker (R-Tenn.) criticized his fellow Republicans, saying the GOP has become "cult-like" in its support of President Donald Trump.

"We're in a strange place. It's becoming a cultish thing, isn't it?" Corker told reporters in Washington, D.C., on Wednesday. "It's not a good place for any party to end up with a cult-like situation as it relates to a president that happens to be purportedly of the same party."

Corker, who is not running for re-election, said some Republican lawmakers are willing to stand up to Trump, but the party leadership is fearful and wary of "poking the bear."

The Senate Foreign Relations Committee chairman has been critical of Trump in the past, calling him an "utterly untruthful president" and saying the White House has become "an adult day care center."

On "Fox News @ Night," conservative columnist Bethany Mandel said Corker has a point about many Republicans being afraid to run afoul of Trump.

"This is sort of Political Calculus 101. You have to be able to keep friends in the White House and make sure that you're able to pass things," Mandel said.

She said it's frustrating that many on the right are hesitant to push back when the administration makes bad moves, but it's also frustrating that many on the left refuse to acknowledge the administration's successes. 

Corker said the Trump administration is "making stuff up as they go along with no coherency to it," specifically referring to Trump's moves on trade.
