USA Today posted an investigation into the way that CEOs and lobbyists make contact with Trump: they join one of his golf clubs. Of course, for $200,000, they could join Mar-a-Lago, his winter residence (he doubled the entry fee after his election).

Dozens of lobbyists, contractors and others who make their living influencing the government pay President Trump’s companies for membership in his private golf clubs, a status that can put them in close contact with the president, a USA TODAY investigation found.

Members of the clubs Trump has visited most often as president — in Florida, New Jersey and Virginia — include at least 50 executives whose companies hold federal contracts and 21 lobbyists and trade group officials. Two-thirds played on one of the 58 days the president was there, according to scores they posted online.

Because membership lists at Trump’s clubs are secret, the public has until now been unable to assess the conflicts they could create. USA TODAY found the names of 4,500 members by reviewing social media and a public website golfers use to track their handicaps, then researched and contacted hundreds to determine whether they had business with the government.

Or, they could rent a $22,000 a night suite at the Trump Hotel located within walking distance of the White House. The building is owned by the federal government and the lease prohibits any profit-making by any elected federal government official, but that doesn’t include Trump apparently.
