David Vitter: Iran advances their nuclear program while playing the US

Some lawmakers are pushing for Congress to hold a vote on any final nuclear deal reached with Iran despite the administration's assiduous efforts to leave Capitol Hill out of the process. However, the Senate would need 67 votes to overcome a likely presidential veto and bar Obama from ordering more congressional sanctions relief for Iran. That high threshold concerns Vitter. "Clearly the administration could benefit from something that puts the burden on us," he said.

"The letter is completely fair and accurate in educating the Iranian leaders who presumably don't know the nuances of representative democracy," Vitter said. "They certainly don't act like they do," he added with a laugh.

David Vitter: Military force against ISIS if Arab ground troops involved

Vitter said that he would support a new AUMF "if we get it right." While Vitter did not specifically address the administration's proposal, he said that any authorization should involve ground troops--primarily from regional Arab countries with U.S. training. "No one wants American boots on the ground to have to lead the way," he said. "But I think we need to recognize this is a serious war, and airstrikes alone aren't going to do it."
