President Obama spoke with his Russian counterpart Dmitry Medvedev Friday morning and the two leaders agreed to meet in Prague, the Czech Republic, on Thursday, April 8, to sign the Treaty between the United States of America and the Russian Federation on Measures to Further Reduction and Limitation of Strategic Offensive Arms (the “New START Treaty”).

White House officials say this was the 14th meeting or phone call between the leaders about the treaty and call it a "landmark agreement" that "advances the security of both nations."

The President will make a statement in the White House briefing room at 10:45am [foxlivestream] along with Secretary of State Hillary Clinton, Defense Secretary Robert Gates and Chairman of the Joint Chiefs of Staff Admiral Mike Mullen.
