President Obama delivered a foreign policy speech today aimed at bolstering public support for the Iran nuclear deal. He also attempted to discredit criticism from those who claim the agreement was a mistake.
"I've had to make a lot of tough calls as president. But whether or not this deal is good for American security is not one of those calls," Obama said during his remarks at American University, located about 10 miles from Capitol Hill.
