Nor is it the first time Trump used his own properties for election-related purposes. Throughout the 2016 presidential race, his campaign (and, ultimately, transition) headquarters were in Trump Tower; he raised the rent by nearly a factor of five once he became the GOP’s nominee and the funds were coming not from his own pocket but from the Republican Party’s. He also memorably held an event at his hotel in Washington, D.C., last September, at which he both promoted the property’s amenities and halfheartedly renounced his participation in the “birtherism” smear campaign against President Obama.

An analysis from CNN concluded that, overall, the Trump campaign spent $12.5 million at Trump properties in the run-up to the election—and that’s just funds from the Trump campaign itself. There are also assorted other expenditures that went to the Trump Organization, such as the money the Secret Service spent (and is in all likelihood still spending) booking flights on Trump’s personal airplanes to accompany the president and his family on their trips around the country. Since taking office, he has directed an additional $6.3 million that was raised for his reelection campaign to the Trump Organization as well. That money is company revenue, so it may not all go into Trump’s own bank account, but some of it almost certainly will.

The notion that Trump could make money running for president (let alone being president) goes back at least 17 years, to when he was considering running for office on the Reform Party ticket. In fact, he himself was the one to suggest it: In a 2000 interview with Forbes, Trump mused that, by planning his campaign stops around a set of appearances he was contracted to make with the motivational speaker Tony Robbins, “it’s very possible that I could be the first presidential candidate to run and make money on it.” He also added that “there’s no way a good businessman” would lose a large sum running for office, as Steve Forbes had done in his 1996 and 2000 bids for the Republican nomination.

Whether Trump actually has made money running for president and during his time in office so far, however, is harder to determine. Based on the financial-disclosure forms he filed with the Office of Government Ethics this year and the Federal Election Commission in prior years, some of Trump’s properties, most notably Mar-a-Lago, have seen increased revenues since he took office. That would certainly suggest he’s making money off of his presidency.

Other indicators, though, seem to suggest that Trump’s new political position is serving as a drag on his business prospects. As I wrote in April, several of Trump’s properties are facing high vacancy rates, declining property values, or both, to the extent that his sons, whom he put in charge of his business when he took office, have reportedly worried that Trump’s controversial tenure will alienate the urbanites who make up his most valuable clientele. Indeed, Scion and American Idea, the two new brands the Trump Organization launched last year in what looks like an attempt to shed associations with its owner’s political baggage, have struggled to get off the ground: After failing to find footholds in St. Louis and Dallas, the imprints’ first locations will be in Cleveland, Mississippi, hardly a tourist mecca.
