Trump says Texas shooting due to "mental health problem," not a gun issue

Asked what policies he might support in response to the shooting at a press conference in Tokyo, Trump said that based on preliminary reports, the gunman was "a very deranged individual, a lot of problems".

He said Sunday's attack "isn't a guns situation" but "a mental health problem at the highest level. It's a very, very sad event".

The lone gunman carrying an assault rifle opened fire after entering First Baptist Church in Sutherland Springs, about 65 km east of San Antonio, killing people that ranged in age from 5 to 72.
