National Review senior editor Jonah Goldberg criticized the Trump administration's mixed messaging when it comes to migrant families being separated at the border.

Goldberg said his confidence that Congress can find a solution is "low," arguing that the Trump administration has botched the situation by not having a unified message. 

"This has been the worst-messaged policy screw-up of any president in my lifetime," he said on "America's Newsroom," calling out Trump for alternating between blaming Democrats and saying he likes the policy. 

"Regardless of what you think of the moral horror at the border ... just his messaging, this has been a disaster."

He said that some officials are "bragging" about the firm implementation of Trump's zero-tolerance policy, while others are taking "deep offense" if accused that the policy is in place.

White House senior policy adviser Stephen Miller has been a strong advocate of the policy, saying in a New York Times interview that it was a "simple decision."

"The message is that no one is exempt from immigration law," Miller said.

Homeland Security Secretary Kirstjen Nielsen, though, had tweeted on Sunday that the Trump administration does not have "a policy of separating families at the border. Period.”

He added that the White House believes it will win politically on immigration issues, but that might not be the case this time. 

"They're right when the issue is about MS-13 and that kind of stuff," Goldberg said. "But these little kids, they're not even MS-three. They're little kids."

Fox News learned Wednesday that the White House is considering executive action that would allow migrant children to stay with their parents who were caught crossing the border illegally.
