Trump Doral Miami is a golf course where the secret service have been charged $17,000/month for a three-bedroom cottage. He keeps the money BTW
Trump Old Post Office LLC - This was leased to him in 2013 by the US General Services Administration. Seems he turned this into the Trump International Hotel.
Trump Ruffin Tower - (Vegas hotel) - in 2002 Phil Ruffin announced that he had partnered with Trump to build the Trump Tower. Second tower has been in talks to be built since 2008, but they wanted the first tower to be sold out first (Liquidity problem?)
Trump Turnberry - Scotland - Golf Course - Again HUGE issues about when Mike Pence went to visit and they had to stay at this hotel. Trump says he has nothing to do with the decision except the detour cost about $600,000. (Again trump profits)
Mar-a-logo Club LLC - 1.2 Million in revenue from secret service staying there. It's had over 100 MILLION in revenues since trump took office, and a big part of that is tax payers paying for trump to go there.
