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

The catastrophic Central Texas floods have claimed at least 121 lives and left 173 missing, as a report reveals that Kerr County officials were repeatedly denied state funding for an emergency flood warning system.

Recordings provided to CBS News showed first responders asking for an emergency alert to be sent, but dispatchers delayed because they needed special authorization.

"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.

In the last nine years, federal funding for a system has been denied to the county as it contends with a tax base hostile to government overspending.

Twice, the Texas Division of Emergency Management turned down Kerr County's requests for money to improve flood warnings.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River rose rapidly.
