Nearly 200 current and former staffers at the Federal Emergency Management Agency (FEMA) warned on Monday that recent changes the Trump Administration has made to the agency could lead to “not only another national catastrophe like Hurricane Katrina, but the effective dissolution of FEMA itself and the abandonment of the American people.”

FEMA employees on Monday warned Congress that the Trump administration's changes and leadership at the agency could harm the U.S. if disaster strikes.

After Hurricane Katrina, Congress passed a law to strengthen the nation’s disaster response. FEMA employees say the Trump administration has reversed that progress.
