President Donald Trump toured the devastation left by flash flooding in central Texas amid growing questions about how local officials responded to the crisis as well as questions about the federal response -- including the fate of the Federal Emergency Management Agency -- that he has so far avoided.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

On Wednesday, hundreds prayed, wept, and held one another at a prayer service, among the first of many somber gatherings to come in the weeks ahead.
