But one has been constructed at Trump International Doonbeg in anticipation of a possible landing of Marine One (and President Donald Trump) this week as the course hosts the DP World Tour’s Irish Open. Like at last year’s Ryder Cup, the president’s appearance might lead to a “different” atmosphere, at least according to Rory McIlroy.

"He's a big fan of golf; he's a wonderful supporter of golf,” McIlroy said. “He's got a beautiful property here in Doonbeg. I wouldn't say it's a true links golf course; it's a bit of an Americanized version of a links course, but it's still a great golf course.

“I think the weekend, especially when he’s here, crowds will be limited. Obviously, there’s a lot that goes on. So, logistically, it provides some challenges, absolutely. But at the same time, if he wants to come and watch the Irish Open, who are we to say no?”
