Obama Says US to Host Next Nuclear Summit in 2016

President Barack Obama says world leaders will convene in the United States in 2016 for the next Nuclear Security Summit.

Obama made the announcement Tuesday as this year's summit wrapped up in the Netherlands.

Although Obama said Chicago would host the 2016 summit, the White House later said no city has been chosen. During his remarks, Obama also referenced the summit being in Washington.

Obama launched the summit series in 2010, hoping to secure materials and keep them out of the hands of terrorists. Since then, the number of countries with enough material to build a nuclear weapon has fallen from 39 to 25.

Obama says the next summit will be a "transition" summit where heads of state will look to hand responsibility for nuclear security to their lower-level officials.
