Brock Long, the administrator of the Federal Emergency Management Agency, will have to reimburse the government for misusing government vehicles by traveling to and from his home — but will keep his job, officials said on Friday.

Mr. Long, a hurricane expert with years of emergency management experience, had come under scrutiny in connection to his frequent commutes between the agency’s headquarters, in Washington, and Hickory, N.C., where his wife and two sons live.

He faced investigations by the inspector general at the Department of Homeland Security, which includes FEMA, as well as by House Republicans, at a time when his agency was grappling with Hurricane Florence’s drubbing descent on the Carolina coast.

The inspector general’s report found that Mr. Long had used government vehicles on trips between his home and work “without proper authorization,” Kirstjen Nielsen, the homeland security secretary, said in a statement on Friday.
