March 12 (UPI) -- Former Vice President Joe Biden appeared to hint at a potential run from for president Tuesday morning speaking before a raucous crowd in Washington, D.C., at the International Association of Fire Fighters union conference.
As the crowd held up placards and chanted "Run, Joe, run," Biden quipped, "Save [that energy] a little longer. I may need it in a few weeks. ... Be careful what you wish for."
