David Richardson, the acting administrator of FEMA, has resigned after six months in the role. The move comes amid criticism over his handling of the Texas floods and pressure from the Trump administration, which sought to reduce the agency’s size.

Richardson was appointed following the ousting of previous acting chief Cameron Hamilton by DHS Secretary Kristi Noem. He stepped down after a period of scrutiny over his response to the July floods that killed 130 people in Texas, including 27 children at a youth camp. During the disaster, Richardson was found to have been on vacation, leading to accusations of incompetence and negligence.

The Trump administration had already planned to remove him from the role, with sources indicating that his departure was anticipated. Richardson’s tenure coincided with efforts to dismantle FEMA, as President Donald Trump called for its elimination after this year’s hurricane season.

Richardson, a former Marine Corps officer, will return to the private sector. His predecessor was fired in May for resisting administration efforts to cut the agency’s budget. The successor of Richardson remains unclear.
