Outrageous. Destructive. Beneath contempt. Treason?

Those are the words being used to describe a letter sent by 47 Republican U.S. Senators to the government of Iran in an attempt to undermine negotiations over its nuclear program.

Our new senator, Cory Gardner, signed this letter. Tell Cory Gardner right now to remove his name from the GOP’s Iran letter.

We all know Washington is regularly mired in partisan gridlock, but this is different. By interfering with the diplomatic efforts of the United States and our allies to dismantle Iran’s nuclear weapons program, Cory Gardner is risking both American lives and the lives of millions of people in the Middle East–and all to score political points. Is this what we want from the Cory Gardner who claimed to be “a new kind of Republican?”

Send a message to Gardner now: let our President do his job. Stop putting lives at risk. Stop embarrassing our country before the eyes of the entire world. Sign on now–and then ask your friends to do the same. We’ll make sure Cory Gardner gets the message loud and clear.
