Government watchdog to review Mar-a-Lago cost and security

The request was made by a group of senators.

In the letter to members of Congress, the GAO also said it would review security screening measures for guests at Mar-a-Lago, how much it costs the Secret Service and Department of Defense to protect Trump in Palm Beach, and whether the president is sending any profits associated with his hotels to the U.S. Treasury.

Trump had promised to donate hotel profits to the Treasury before taking office.
