Federal Emergency Management Agency Administrator Deanne Criswell told Congress on Tuesday that she will request an investigation from the Department of Homeland Security’s inspector general after the agency terminated an employee for withholding services to hurricane victims for political reasons.

Criswell’s declaration came during testimony before a House Transportation and Infrastructure subcommittee hearing, her first of two congressional hearings on Tuesday, where she directly addressed claims made by the former employee, Marn’i Washington.
