Donald Trump will spend a few days away from his campaign when he flies to Scotland Thursday to promote his company's golf course on the country’s southwestern coast.

Trump, whose poll numbers are slipping, with his campaign reportedly in desperate need of cash, hasn’t planned on meeting any dignitaries, his team said. The presumptive Republican presidential nominee who lands in Scotland Friday has a helicopter landing at his luxury resort, a ceremonial ribbon cutting and family photo, and a news conference planned, reports said.

GOP members, who are already worried about the party's presumptive nominee, now fear that the real estate mogul’s attention will be divided between his business and his general election campaign. “I'm not sure what the purpose of the trip is,” Senator John Thune said, according to the Associated Press (AP), adding that he hopes Trump “would get back here quickly.”

Trump's son Eric, who oversaw the two-year $300 million renovation at the Trump Turnberry golf course, dismissed those concerns in an interview with AP. He said “the eyes of the world” will be on his father during the trip.

“The Turnberry course is one of the crown jewels of the golf world and is now one of the crown jewels of our family's properties,” Eric Trump said. “He's over there to inspect the course and to support his son who put a tremendous amount of time and energy into the project.”

Trump will visit the Turnberry course, bought in 2014, on Friday and another course in Aberdeen Saturday, before returning to the U.S. Eric Trump stressed that the trip was important.

Trump not meeting with any foreign dignitary while on foreign soil stands in contrast to previous presidential nominees’ foreign trips. In 2012 Mitt Romney met with British Prime Minister David Cameron. Then-Senator Barack Obama and German Chancellor Angela Merkel had a meeting in 2008.
