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 Friday 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 has ordered all flags under state control to be lowered to half-staff in honor of the Fort Hood victims.
Perry and Cruz met with wounded soldiers being treated at Darnall Army Medical Center at Fort Hood. Meanwhile, four victims remained hospitalized Friday at Scott & White Memorial Hospital in Temple.
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 says one injured soldier took steps Wednesday to protect others from the shooter.
On Thursday, Sen. John Cornyn visited Fort Hood and spoke alongside Lt. Gen. Mark Milley, commanding general of the Army post.
At 3 p.m. Friday afternoon, Lt. Gen. Mark Milley, the commanding general of the post, is expected to confirm the list of fatalities. A memorial service is being planned for next week.
