evidence: From the Florida recount to overseeing the U.S. response to the Ebola pandemic, Ron Klain is bringing a battle-tested resume to bear as he navigates Biden's ambitious agenda as his chief of staff. [...] WHIPPLE: Ron Klain comes in uniquely well prepared for this job - chief of staff to two vice presidents, experience in the White House, knowing Capitol Hill, having been the Ebola czar and, most important, having a strong relationship with Joe Biden but not being a very close friend. [...] LIASSON: Klain has known Biden forever. He was an intern in Biden's Senate office, later his chief of staff, the same role he served in for Vice President Al Gore. Klain oversaw the execution of the Obama stimulus plan, and he's worked in every modern Democratic presidential campaign. His role in the 2000 Florida recount for Gore was portrayed by Kevin Spacey in an HBO movie.
