Charles Krauthammer said Friday on “Special Report with Bret Baier” that President Obama is "negotiating out of weakness and desperation" when he says that Congress must hold off on imposing new sanctions on Iran while the administration continues to negotiate a nuclear deal with that country.

"[Obama] says, 'nobody doubts that I have the ability to get new sanctions. True," the syndicated columnist and Fox News contributor said. "But nobody in the world believes that he has the willingness to get these sanctions.

"Nobody, including the Iranians, has any faith in the fact that he will actually impose sanctions. The Iranians know that, and that's why they know that he's negotiating out of weakness and desperation."
