The golf-loving American president is to attend the opening day of action at Bethpage Black on Friday afternoon as the US try to regain the trophy they lost in Rome two years ago.
He is the first sitting president to attend the Ryder Cup and his presence is sure to fuel American patriotism -- not to mention creating a major security headache.
It's certainly fuelled DeChambeau, who was announced on the eve of the tournament to be in the Americans' opening pairing in the foursomes alongside Justin Thomas.
"I think he'll be a great force for us to get a lot of people on our side ... I hope he will inspire us to victory," said DeChambeau of the President's scheduled appearance.
"It's going to be an electric environment."
DeChambeau and Thomas will be taking on the fiery European combination of Jon Rahm and Tyrrell Hatton amid what is expected to be a feverish and potentially hostile atmosphere generated by the home support.
That match will be followed by Europeans Ludvig Aberg and Matt Fitzpatrick taking on US world No.1 Scottie Scheffler and Russell Henley, before the key visiting pairing of Rory McIlroy and Tommy Fleetwood take on the hosts' Collin Morikawa and Harris English.
The line-up for the first session will be completed as Europe's Robert MacIntyre and Viktor Hovland tackle Xander Schauffele and Patrick Cantlay.
DeChambeau, who played with Trump for a video on his YouTube channel, is ready to harness the atmosphere generated by the President's appearance, saying: "I think it will be interesting and exciting to see how the crowd and everybody reacts."
Europe have won 10 of the last 14 Ryder Cups dating back to 1995 but come into the week as underdogs against a US squad eager to reclaim the trophy on home soil.
As the most experienced player at this year's Ryder Cup, Rory McIlroy has taken on the leadership mantle for Europe and the Northern Irishman issued an eve-of-event rallying call on Thursday, saying the holders were playing for history.
"We are playing for history and we're playing for the players that came before us," said McIlroy, who has been to the Ryder Cup more than any player on either team.
"We are also playing for the guys that are going to come behind us, as well, the young boys that are dreaming of becoming European Ryder Cup players. We want to try to leave a legacy for them."
That poetic passion is a far cry from his first encounter with one of golf's most treasured traditions, which he dismissively called an "exhibition" event before his 2010 debut.
The then-21-year-old got a wakeup call as he stepped into the team room at Celtic Manor.
"I just saw how much it meant to everyone," he said. "I was like, 'Maybe I got this wrong'."
McIlroy's standing as winner of all four majors makes him a huge figure in the European camp.
"He's a leader. He's potentially the greatest European golfer of all time," Scotsman Robert MacIntyre said.
"I've looked up to him since I was young, and I've got no problem walking behind Rory McIlroy if he's leading the charge."
