President Donald Trump is touring 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.

The floods that swept south central Texas last week have killed at least 120 people, with 160 still missing. First responders have had to navigate piles of debris as they search through the wreckage for survivors.
