Homeland Security Secretary Kristi Noem joined Texas Governor Greg Abbott during a press conference on Saturday to announce comprehensive federal disaster response, conveying that President Donald Trump is "absolutely heartbroken by what has happened here in Texas, and the loss of life is absolutely devastating to him and Melania."

At least 24 people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding. Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.

Hundreds of residents, campers and visitors were plucked to safety after the Guadalupe River rapidly swelled in Texas Hill Country with little warning.
