President Donald Trump is traveling to central Texas on Friday to survey the aftermath of a catastrophic flood that has killed more than 100 people and put his administration on the sudden defensive over its emergency response efforts.

US President Donald Trump visited central Texas on Friday, clapping back again at the criticism of his policy and federal response to the July 4 major flooding that left at least 121 dead and more than 150 others missing.

Trump praised Republican Governor Greg Abbott and other local officials for their "incredible" response to the flooding in Texas but criticized elected Democrats in California when wildfires devastated Los Angeles in January.
