Cotton: 'No regrets' about GOP Iran letter

Sen. Tom Cotton says he has “no regrets” about the Republican Senate letter sent to Iran’s leaders, warning them that any nuclear deal they reach with the United States could be modified by Congress or a future president.
“Iran’s leaders need to hear the message loud and clear,” the Arkansas Republican said Sunday on CBS’s “Face the Nation,” defending a letter he signed with 46 other Republican senators that has led to major blowback.
