Hosted by

President Obama today went to American University in Washington, DC, where President John F. Kennedy urged support for the nuclear test-ban treaty during the Cold War.  Mr. Obama made a connection to the nuclear deal with Iran, "The agreement now reached between the international community and the Islamic Republic of Iran, builds on this tradition of strong principled diplomacy.... Every nation in the world, that has commented publicly, with the exception of the Israeli government, has expressed support." Steven Mufson is White House correspondent for the Washington Post.
