ORLANDO, Fla. - Vice President Joe Biden is addressing the nation's mayors at their annual conference.
Biden's speech comes Friday toward the end of the four-day U.S. Conference of Mayors meeting in Orlando.
Dozens of mayors have weighed in on urban economics, immigration reform and the 2012 election campaign during the conference.
They've also heard speeches from two Cabinet members: U.S. Education Secretary Arne Duncan and U.S. Housing and Urban Development Secretary Shaun Donovan.
