Since Trump took office, he has visited his own properties on 355 days. Secret Service agents come with him. And Trump’s company charges them. Last November, in response to a public records request from the group Property of the People, the Secret Service released a list of 56 payments it had made to Trump’s companies. All were from 2017. But the list was cryptic. It didn’t say what the Secret Service had been charged for. In some cases, it didn’t even say which Trump property had been paid.

The Post tried to decode this list. One surprise: at least 20 of the payments to "Trump National Golf Club" — worth $63,700 — weren’t to a golf club at all. Other documents, already released, showed they were payments to Mar-a-Lago. The Post learned that many of them were hotel bills for $650 per night — a rate far higher than the usual limits on federal hotel spending. There is no legal limit on what the Secret Service may spend on hotel rooms while its agents are protecting the president.

In four other cases, the dollar amount was a giveaway: All included a tax of 6.875 percent, which was the sales tax in New Jersey in 2017. That pointed to Trump National Golf Club Bedminster, which is the only Trump property in New Jersey that he has visited as president.
