Former U.S. secretary of state Hilary Clinton has joined the chorus of criticism against the letter signed by 46 U.S. senators addressed to Iran’s Supreme Leader. She slammed the move, calling it “out of step” with “traditions of American leadership”.

“The recent letter from Republican senators was out of step with the best traditions of American leadership, and one has to ask what was the purpose of this letter?” Clinton told reporters; “Either these senators were trying to be helpful to the Iranians or harmful to the commander-in-chief in the midst of high-stakes international diplomacy. Either answer does discredit to the letter’s signatories.”

Meanwhile, U.S. Vice President Joe Biden also slammed the letter, saying it was “expressly designed to undercut a sitting president in the midst of sensitive international negotiations” and that it was in this sense “beneath the dignity” of the U.S. Congress.

The letter purports that any deal with the Obama administration will only be valid while Barack Obama is in the White House.

Iran is in the process of negotiating with the 5+1 delegations to resolve all nuclear disputes. Iran has continuously held that its nuclear program is peaceful and it has no intention of developing nuclear weapons.
