Former President George W. Bush and his wife, Laura, have visited wounded soldiers and their families after the mass shooting at Fort Hood.

The Bushes made their private visit to Fort Hood's Darnall Army Medical Center on Friday night. Bush spokesman David Sherzer said in an e-mail that the couple thanked Fort Hood's military leaders and hospital staff for the "amazing care they are providing."

An Army psychiatrist, Maj. Nidal Malik Hasan, is accused of killing 13 people and wounding 29 others in a shooting rampage Thursday at a Soldier Readiness Processing Center at Fort Hood. Hasan is hospitalized, under guard.
