President Donald Trump says the mass shooting at a Texas church is the result of a "mental health problem at the highest level."
Speaking at an event with the Japanese prime minister in Tokyo on Monday, Trump described the gunman as a "very deranged individual."
Authorities say 26 people were killed and about 20 others were wounded Sunday after a man opened fire inside the First Baptist Church in Sutherland Springs.
Officials identified the shooter to The Associated Press as Devin Kelley.
Authorities have not yet determined a motive for the shooting, and have not broached the topic of the gunman's mental health.
