Representatives Elise Stefanik, Chair of the House Republican Conference, James Comer, House Committee on Oversight and Reform Ranking Member, and Mike Turner, House Permanent Select Committee on Intelligence Ranking Member co-signed the letter.“We write to conduct oversight of the Federal Bureau of Investigation’s (FBI) use of Government aircraft and compliance with the applicable Federal regulations and requirements,” reads the letter, first obtained by Fox News. “We have questions about whether you are properly reimbursing federal taxpayers for your personal travel aboard government aircraft.”

This was not the director’s first round-trip getaway using the FBI plane. On June 2, the plane traveled to Saranac Lake on June 2 and returned to Washington, D.C. on June 5. Wray is required to reimburse the cost of a coach class airline fare when the plane is used for personal trips, but it costs several thousand dollars per hour to operate the Gulfstream, the paper noted.

Government plane travel is authorized for “official purposes” and can only be used for informal travel when no commercial air is available or would cost more, according to Office of Management and Budget (OMB) guidance, Fox News noted.
