Earlier this summer, according to a staffer, a group of Saudi royals stayed at the resort for about a week at the tail end of extended travel, bringing a party of 25 people and more than a hundred pieces of luggage.

Lobbyists representing the Saudi government reserved blocks of rooms at President Trump’s Washington, D.C., hotel within a month of Trump’s election in 2016 — paying for an estimated 500 nights at the luxury hotel in just three months, according to organizers of the trips and documents obtained by The Washington Post.

At the time, these lobbyists were reserving large numbers of D.C.-area hotel rooms as part of an unorthodox campaign that offered U.S. military veterans a free trip to Washington — then sent them to Capitol Hill to lobby against a law the Saudis opposed, according to veterans and organizers.

At first, lobbyists for the Saudis put the veterans up in Northern Virginia. Then, in December 2016, they switched most of their business to the Trump International Hotel in downtown Washington. In all, the lobbyists spent more than $270,000 to house six groups of visiting veterans at the Trump hotel, which Trump still owns.

Those bookings have fueled a pair of federal lawsuits alleging Trump violated the Constitution by taking improper payments from foreign governments.

During this period, records show, the average nightly rate at the hotel was $768. The lobbyists who ran the trips say they chose Trump’s hotel strictly because it offered a discount from that rate and had rooms available, not to curry favor with Trump.

President Donald Trump’s hotel in New York City earlier this year reversed a two-year trend of declining rental revenue after travelers with crown prince of Saudi Arabia booked rooms there, a new report said Friday.

The Trump International Hotel saw a 13-percent increase in rental revenue in the first three months of this year after several people accompanying Crown Prince Mohammed bin Salman stayed for five days in March, according to The Washington Post.

The article cited a letter from the hotel’s general manager, Prince Sanders, who noted that the Saudi prince himself had not stayed in the hotel because its suites were not large enough to accommodate him or other members of the royal family. But the bookings from people traveling with him were enough to increase the hotel’s revenue for the first financial quarter.
