"Right now, that money has nothing to do with what you see behind us", Long said from FEMA's response center in Washington.
The actions by Long, the US government's lead disaster official as the country braces for Hurricane Florence, have been called into question by the inspector general over whether taxpayers have inappropriately footed the bill for his travel, an issue that has tripped up a number of current and former top Trump administration officials.

"All questions about any potential investigation by the Office of the Inspector General should be directed to the [inspector general]".
"The secretary is confident in the leadership at FEMA and their proven disaster management ability", he added. Its responses to past hurricanes - particularly Maria and Katrina, which both had death tolls in the thousands - have been the subject of severe criticism.
