Army Secretary John M. McHugh, left, accompanied by Army Chief of Staff Gen Raymond Odierno, pauses on Capitol Hill in Washington, Thursday, April 3, 2014, as they updated members of the Senate Armed Services Committee about the deadly shooting rampage by a soldier yesterday at Fort Hood in Texas. An Iraq War veteran being treated for mental illness was the gunman who opened fire at Fort Hood, killing three people and wounding 16 others before committing suicide, in an attack on the same Texas military base where more than a dozen people were slain in 2009.
