Texas Gov. Rick Perry and U.S. Sen Ted Cruz say they've visited with military personnel wounded in Wednesday's shooting at Fort Hood that left four dead and 16 wounded.
Perry told a media gathering that he saw the "resilience" of military families recovering from the mass shooting. He says there "aren't any easy answers" to what prompted Spc. Ivan Lopez to fire on fellow soldiers. Lopez killed three people before fatally shooting himself.
Perry and Cruz met with wounded soldiers being treated at Darnall Army Medical Center at Fort Hood.
Cruz described Fort Hood as a "national treasure" and said in meeting with Army personnel at the base he heard stories of bravery and courage. He noted one injured soldier, who took steps Wednesday to protect others from the shooter.
