White House says Iran nuclear talks 'to go down to the wire'
US President Barack Obama is receiving frequent briefings on international talks in Switzerland aimed at curbing Iran's nuclear program, and has been providing guidance to US negotiators when needed, a White House spokesman said on Monday.
"I'm not going to presuppose failure. Those negotiations are going to go down to the wire," White House spokesman Eric Schultz told reporters traveling on Air Force One to Boston with Obama.
