Joe Biden's Potential Presidential Campaign "Ramping Up," Says Adviser

Vice President Joe Biden "is 90 percent in" when it comes to making a decision about running for the White House, according to one political adviser. "His political team has been ramping up in recent days, entering what they call a more active phase," Cecilia Vega reported Sunday on This Week. "In camp Biden, there are discussions about fundraising and launching a political action committee, and while the vice president himself hasn't authorized any of these moves, one adviser tells ABC News he believes Biden is 90 percent in," Vega said.
