Trump and first lady Melania Trump visited Texas for an aerial tour of the sites of the catastrophic flooding, which killed at least 120 people while more than 170 remain missing. The president will also participate in a roundtable discussion with first responders and local officials.

Some governors and mayors are concerned over how current or potential cuts to agencies will impact how the government can respond in the future to major weather events.

The July Fourth flood moved so quickly in the middle of the night that it caught many off guard in a county that lacked a warning system.

July 9 (Reuters) - U.S. Homeland Security Secretary Kristi Noem called on Wednesday for the Federal Emergency Management Agency to be eliminated in its current form, even as the disaster-relief agency deployed specialists and supplies to Texas to help respond to devastating floods.

The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.

A week after catastrophic floods in Central Texas, key questions remain unanswered about how state and local officials prepared for and responded to the disaster.

As Trump heads to Texas to see the impact of last week’s deadly flash floods, the White House has backed away from plans to abolish FEMA, officials said.
