By Trevor Hunnicutt and Maria Alejandra CardonaKERRVILLE, Texas (Reuters) -President Donald Trump defended the state and federal response to deadly flash flooding in Texas on Friday as he visited the stricken Hill Country region,

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Search crews continued the grueling task of recovering the missing as more potential flash flooding threatened Texas Hill Country.

The reporter said that several families were angry because they felt that alerts for the flood did not go out in time.

"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.

The Houston Texans were the first to announce their donations on Saturday, July 5, with more coming throughout the week. The Dallas Cowboys and the NFL Foundation joined the Texans on Sunday, July 6, with each contributing $500,000 in a $1.5 million total donation.

Over the last decade, an array of local and state agencies have missed opportunities to fund a flood warning system intended to avert the type of disaster that swept away dozens in Kerr County, Texas.

A Kerrville-area river authority executed a contract for a flood warning system that would have been used to help with emergency response, local officials said.
