President Trump's sons' visit to Dubai this week has costed taxpayers a minimum of $73,000 in security costs, according to government purchase orders viewed by CBS News. The purchase orders describe the costs for United States Secret Service agents to stay at hotels close to the Trump property and car service for the trip listed as being from March 26 through April 8.

The trip is for the family business and not related to any government work.

Secret Service spokesperson Mason Brayman emailed CBS News in response to a request for comment on the trip: "The Secret Service is conducting a protective operation in the UAE. As a matter of practice we do not comment on the specifics of protectee's trips."
