Arkansas Sen. Tom Cotton blasted the nuclear deal with Iran on Tuesday, saying it will pave the way for the country to get a nuclear weapon.
The Republican, who sits on the Senate Committee on Foreign Affairs, also predicted that Congress would end up killing the deal.
"The American people are going to repudiate this deal, and I believe Congress will kill the deal," he said on MSNBC shortly after negotiators announced from Vienna they had reached a long-term agreement to curb Tehran's nuclear program in exchange for sanctions relief.
Cotton — one of the most outspoken lawmakers against the negotiations with Iran — also said he does not believe the deal is tough enough on Iran.
"When we started down this path, [Obama] said the goal was to dismantle Iran's nuclear program," Cotton added. "This leaves the nuclear program entirely intact. They can get a nuclear weapon if they violate the deal, as they've done with every agreement in the past, or they can get a nuclear weapon if they follow the deal in a mere 10 to 15 years."
In March, he and dozens of GOP senators sent a letter to Iran's leaders warning them that any deal signed by the Obama administration could be undone by a future Republican president if it were deemed unacceptable. Congress now has 60 days to review the deal, and either accept it or vote to disapprove of it.
