Biden Nears Decision Time

In or Out? Analysts Beg off the 2016 Biden Guessing Game 1:14

Vice President Joe Biden is nearing a decision on if he will enter the presidential race, which could come within 48 hours, two sources told NBC News.

Biden has been contemplating a presidential run for months and has delayed an announcement beyond supposed time frames multiple times before. Missing this deadline, of course, could happen again.

In addition to when, the big unknown is what Biden's decision will be: Is he in or is he out?

Biden's public schedule gives little indication of his decision. He traveled from his home in Delaware on Monday morning to Washington, where he was to address a climate change summit in the afternoon.

If Biden does announce within the next two days, his decision would come before current front-runner, Hillary Clinton, appears before the House committee charged with investigating the Benghazi attacks more than three years ago.

In a signal that he is considering running, Biden spoke with International Association of Fire Fighters President Harold Schaitberger for about 20 minutes Friday. Biden said he was strongly considering running and was trying to gauge the support of unions, a source said.
