US president Donald Trump arrived to watch the fourballs on day one of the Ryder Cup amid a partisan atmosphere at Bethpage Black.

Air Force One flew over the course just outside New York at approximately 11:00 EDT (16:00 BST) and landed at a nearby airport.

Trump, an avid golfer and fan, arrived on the course 45 minutes later where he waved to the crowds, with some supporters chanting his name along with “U-S-A” while a number of others booed.

With Europe 3-1 up on the USA following the foursomes a fan quipped Trump should have brought his clubs.

“I think we’ll be ok,” Trump told reporters as he disembarked Air Force One. “All great golfers.”

He was accompanied by his granddaughter Kai, who is a keen amateur golfer and is set to play at the University of Miami in 2026.

Security had been substantially increased for Trump’s visit with the US Secret Service, CIA and FBI reported to be involved, external in a cross-agency operation.

Earlier this month the US Open men’s tennis final was delayed by 30 minutes because of extra security measures put in place for a visit by the president.
