President Barack Obama spent nearly two hours visiting wounded U.S. soldiers Friday afternoon.

The president met with 19 soldiers being treated at Walter Reed Army Medical Center, as well as the families of three soldiers in intensive care, and hospital staff. He also awarded two Purple Hearts.

The president's visit came a day after an Army psychiatrist who once trained at Walter Reed hospital allegedly killed 13 people at Fort Hood. The White House says the hospital visit was planned before the shootings.

Friday's visit was Obama's first to Walter Reed since taking office, though he visited as a presidential candidate.
