President Barack Obama reaches down from a podium in the East Room of the White House to shake hands with Rep. Jim Langevin (D-RI). Langevin is the nation's first quadriplegic to serve in the U.S. House of Representatives.
On March 9, 2009, Langevin and others celebrated the President's signing of an Executive Order that reversed the U.S. ban on stem-cell research.
