"The first lady and I are here in Texas to express the love and support and the anguish of our entire nation in the aftermath of this really horrific and deadly flood," Trump said as he spoke at a roundtable event with first responders and local officials.

Emergency crews suspended their search for victims of catastrophic flooding in central Texas on Sunday morning amid new warnings that additional rain would again cause waterways to surge.

In the area around Kerrville, approximately 10 inches (250mm) of rain fell in a matter of hours on Friday.

In Kerr County, Trump was greeted by Gov. Greg Abbott, who on Friday announced the federal government updated Trump's disaster declaration to include more counties. Abbott said the move "will provide critical assistance to Texans and communities impacted by the devastating flooding."
