Sources: Biden to Announce 2016 Decision Within 48 Hours

Vice President Joe Biden is expected to decide whether to enter the 2016 presidential race within the next 48 hours or sooner, two sources told NBC News Monday.

Biden has been considering a run for months and has blown past several self-imposed deadlines. His public schedule on Monday offered little indication of his decision. He traveled from his home in Delaware to Washington where he will address a climate change summit Monday afternoon.

In a signal that he is considering running, Biden spoke with International Association of Fire Fighters President Harold Schaitberger on Friday. 

Meanwhile, Sen. Dick Durbin said on MSNBC's "Morning Joe" Monday he's not sure Joe Biden could win the Democratic presidential nomination if he enters the race now.

Asked whether Biden could win the nomination by jumping in now, Durbin said he was "not sure ... I would say at this point he has not had the starting structure" that Clinton has.
