David Richardson, acting chief of FEMA, announced he will resign after hurricane season amid public criticism and internal frustration over his leadership.

Richardson, a loyalist to DHS Secretary Kristi Noem with no disaster-management experience, faced scrutiny for incidents like being unaware of the U.S. hurricane season and being largely absent during catastrophic Texas floods in July.

He will be replaced by Karen Evans, a Trump administration ally and DHS chief of staff, starting December 1.

Richardson defended his tenure, saying he stepped into the role weeks before hurricane season when no one else would and coordinated responses remotely during disasters, CNN has reported.

His departure highlights ongoing leadership challenges at FEMA as DHS plans reforms that could reshape the agency’s future.
