Multiple urban search and rescue teams from across the country that responded to the deadly floods in central Texas told CNN they were not deployed by the Federal Emergency Management Agency until at least Monday evening — days after any victim had been found alive.

There are questions over why oversight was eased at Mystic Camp as it expanded in a hazardous floodplain, the AP reported.

The president and first lady visited Kerrville to meet local officials and families of the victims of the recent flooding. Trump promised federal support, but his team emphasized the state's role.

The Homeland Security chief denied that a memo she issued in June requiring her to approve FEMA expenditures over $100,000 caused the agency to move more slowly.
