What’s more, Trump properties are expensive – and the agency is not allowed to accept any funding or resources that Congress hasn’t appropriated. That would include hotel rooms at Trump-owned properties, said another former Secret Service director, W. Ralph Basham, who says these regulations would guard the agency from any possible compromise of its protective mission.

Since Trump is unable to toss the Secret Service any freebies, it would be up to him to decide to adjust his travel. “The president could prevent this problem by changing his behavior,” said Walter Shaub, who resigned last month from his position as director of the Office of Government Ethics. “He could stay in town and do some work – and not go off frolicking on golf boondoggles to his own properties.”
