Syndicated columnist and Fox News contributor Charles Krauthammer said Thursday on "Special Report with Bret Baier" that the way the United States paid Iran cash in the middle of the night, clandestinely, was "the way it's done by gangsters."

"They were doing ransom, they didn't want anyone to know and they had to go around the law and the Congress," Krauthammer added. "The Congress didn't know."

President Obama, who spoke at the Pentagon Thursday, said that because the U.S. didn't have a relationship with Iran, it had to be done this way.  

Krauthammer called the move 'highly embarrassing' and reacted to Obama's comments, saying "I have to admit, he's rather good with words, he made it sound like this had just completely natural." 

He added the swapping of money and hostages was like a scene out of a movie.

"They had to wait for the ransom to arrive, that's what happens when you ransom a hostage, you wait until the cash arrives and then the guy, in all the movies, is released across the field, you know, where he's being released," he said. "For them to try and pretend this was anything other than a ransom is laughable, and I think it hurts their credibility."
