Former president Bill Clinton said in an interview broadcast Sunday that President Obama is right not to negotiate with Republicans over the debt ceiling.

"If I were the president, I wouldn't negotiate over these draconian cuts that are gonna take food off the table of low-income working people, while they leave all the agricultural subsidies in for high-income farmers and everything else. I just think it's-- it's chilling to me," Clinton said on ABC's "This Week with George Stephanopoulos."

Clinton also weighed in on foreign policy, saying there is a better chance for meaningful engagement with Iran now than there was during his presidency.

"President Obama has enough time to make something out of this," Clinton said. "So I think they should keep the door open."

Obama spoke Friday via telephone to newly minted Iranian President Hassan Rouhani. It was the first conversation between leaders of the two countries in decades.
