The Trump administration and its predecessors will face scrutiny over the disaster that has killed more than 100 people.

The White House rebuked critics for raising questions about the administration’s efforts to shrink federal agencies that deal with disaster preparedness and response.

Mr. Trump said his administration was working with state and local officials and that Department of Homeland Security Secretary Kristi Noem would be arriving in Texas shortly. DHS oversees the Federal Emergency Management Agency.
