Right-wing Fox News slams Republicans for sending letter to Iran

Fox News host Greta Van Susteren on Sunday blasted Republican senators for sending a "horrific" letter to Iran, and attempting an "end run" around the president.

David Remnick, editor of , told an ABC News panel that the 46 senators who joined Sen. Tom Cotton's (R-AR) letter undermine President Barack Obama's negotiations with Iran had made a "horrendous" mistake.

"If you read the text of the letter, it is the most condescending, infantile text assuming that the leaders of Iran — whatever you may think of them, and there's a lot on the record to think terribly of them — that somehow, that they have no idea what the American system is all about," Remnick explained. "It's an absurd comical exercise."

Susteren agreed: "I think that letter was horrific."

"It end runs the president, which I think is terrible," she said. "I think they could have achieved the same goal without sending a letter becoming pen pals with the leadership of Iran."

The Fox News host also condemned President Obama for trying to "end run the United States Senate and not calling this a treaty."
