The amount is $1,100 per month, an amount that the Secret Service calculated because of a requirement in the US Constitution that the Secret Service pay a fair value for space they require. The reason that past presidents did not set values for this is, because as far as I know , no past president was in the previous business of being a landlord. However, Trump was and is a landlord, so the Constitution requires that a fair rent be paid for the use of his properties, so what did he do ? When he became president, the membership costs at his resorts doubled , which probably means that the rent that the Secret Service has to pay at those resorts has doubled.
