Republican presidential candidate Carly Fiorina criticized how the Obama administration is handling nuclear negotiations with Iran.

According to the former CEO of Hewlett-Packard, U.S. negotiators have "caved" on all of the goals set up by President Obama.

"I would have walked away because if you can't walk away from the negotiating table, the other side just keeps negotiating," she said on ABC Sunday. "And that's precisely what's happened. We have caved on every major goal that President Obama set."

Fiorina also added that she would "walk away" from the negotiation table unless the Iranians are "prepared to open every nuclear facility, every uranium enrichment facility to full and unfettered inspections, that we will make it as difficult as possible for them to move money around the global financial system."

In addition, the U.S. should recognize that China and Russia "have not been negotiating on our side of the table" because it is "in those two countries' interests that Iran's economy is open."

Reports surfaced Sunday that a provisional deal was reached between Iran and five other world powers to curb Tehran's nuclear weapons program in exchange for sanctions relief.

Fiorina launched her presidential campaign in May. In a RealClearPolitics average of polls, she garners just two percent of support.
