Peter Gaynor, who is the agency's deputy administrator, will take over for Long after he departs.
Brock Long, the administrator of the Federal Emergency Management Administration(FEMA), announced Thursday that he was resigning from his position, saying "it is time for me to go home to my family."
In a statement, Long said FEMA had provided assistance on "more than 200 declared disasters" and thanked President Donald Trump, Vice President Mike Pence and Homeland Security Secretary Kirstjen Nielsen, whom he said "have been extremely supportive of me, the FEMA workforce and our mission."
"As a career emergency management professional, I could not be prouder to have worked alongside the devoted, hardworking men and women of FEMA for the past two years," Long added. " ... I leave knowing the Agency is in good hands."
Long had been investigated by the Department of Homeland Security's internal watchdog last year over allegations that he inappropriately used government vehicles to travel to his home in North Carolina. Officials found he had misused vehicles, but Long was not asked to resign, and he agreed to reimburse the government.
Great to meet with Puerto Rico Governor @RicardoRossello today in D.C. @FEMA is currently their largest employer and continuing our strong partnership is vital to disaster recovery after #HurricaneMaria. pic.twitter.com/wHGPFlZFZi— Brock Long (@FEMA_Brock) February 6, 2019
