Long said the inspector general was looking into vehicle usage, but he didn't confirm that the review concerned his use of an official vehicle.
This, after an internal report alleged Long used government vehicles and resources for personal use.
"What concerns me the most is trying to get to the people who didn't evacuate and that's incredibly hard to do, so we can't put our own people in danger", said administrator Brock Long, who spoke to CBS News right before he went to brief the president. "Bottom line is if we made mistakes on the way a program is run, then we'll work with the OIG to get those corrected", Long said. "Doing something unethical is not part of my DNA and it's not part of my track record my whole entire career so we'll work with the OIG", he continued. The administrator's trips home to North Carolina have also drawn the ire of his boss, DHS secretary Kirstjen Nielsen, who reportedly confronted him about them this summer. "At this time, we are fully focused on preparing for, responding to, and recovering from Hurricane Florence and the storms in the Pacific", Houlton told ABC News.
White House press secretary Sarah Sanders declined to comment to CNN on conversations about Long's future, and referred questions to DHS. She called Long "an experienced and respected emergency manager".
