Those charges, compiled here for the first time, show that Trump has an unprecedented — and largely hidden — business relationship with his own government. When Trump visits his clubs in Palm Beach, Fla., and Bedminster, N.J., the service needs space to post guards and store equipment.

Trump’s company says it charges only minimal fees. But Secret Service records do not show that.

At Trump’s Mar-a-Lago Club, the Secret Service was charged the $650 rate dozens of times in 2017, and a different rate, $396.15, dozens more times in 2018, according to documents from Trump’s visits.

And at the Trump National Golf Club Bedminster, the Secret Service was charged $17,000 a month to use a three-bedroom cottage on the property, an unusually high rent for homes in that area, according to receipts from 2017. Trump’s company billed the government even for days when Trump wasn’t there.
