Four Democratic senators are calling for an investigation into who has received Air Force One tours under the Trump administration, following reporting by BuzzFeed News that found that some members of the president’s private Florida clubs appeared to have received those tours.

In a letter to the inspectors general of the Air Force and Department of Defense, Sens. Elizabeth Warren of Massachusetts, Ben Cardin of Maryland, Richard Blumenthal of Connecticut, and Sheldon Whitehouse of Rhode Island cite the BuzzFeed News report as “particularly troubling.”

“If true, these reports could mean that the President or his family have used government property for private gain — giving tours of Air Force One as a perk for club membership — or that some citizens have potentially been able to buy access to Air Force One via their personal payments to the President’s private club,” the letter states.

“This use of Air Force One would not only raise questions about readiness, security, and taxpayer cost, but it also violates the basic principle against using public office for private gain, and could constitute a violation of federal ethics rules…Moreover, federal ethics law prohibits the use of government property, including Air Force One, ‘for other than authorized purposes.'”
