"In some ways it's the G6 plus Donald Trump." @CochraneCBC reports on the divisions between G7 nations meeting in Sicily right now @cbchh pic.twitter.com/rOJYOAMAV4

Whether because he was exhausted or trying to underscore the distance between himself and other world leaders, President Donald Trump chose to use his favorite vehicle — a golf cart — rather than walk with the rest of the G7 leaders in Taormina, Sicily, on the final day of his international tour.

After first making the leaders of Britain, Canada, France, Italy, Germany and Japan wait for a group photo Saturday in the hilltop town, according to The Times of London, Trump moved front and center for the picture.

The rest of the group then wound their way about a quarter of a mile to a piazza past small crowds and media. Trump, however, reportedly waited for the electric cart to deliver him to the site. He finally disembarked to join the other leaders for the final walk to the G7 summit venue in a former monastery, now the San Domenico hotel, The Times reported.

Trump and wife Melania also rode a golf cart with Saudi Arabia’s King Salman bin Abdulaziz Al Saud through the corridors of the National Museum during the first stop on his tour. (See the video below.)

The Times said Trump’s choice in Sicily showed the American president was “out of step” with his fellow leaders. That same day, the president announced he would delay a decision on whether or not the U.S. would stay in the Paris climate accords, despite pressure from the other leaders. CBC’s David Cochrane called the summit “G-6 plus Donald Trump.”

But the 70-year-old president — the oldest of the seven leaders — may not have been up to the walk physically. When he made gaffes at the start of his trip (telling Israel’s president that he had just left the Middle East after his first stop in Saudi Arabia), a White House aide chalked it up to exhaustion.

Trump blasted rival Hillary Clinton during the presidential campaign, saying she didn’t have the stamina to be president, even though she traveled to more than 110 nations as secretary of state.

Trump has some unusual ideas about exercise. He reportedly thinks people are born with a finite amount of physical energy, and exercise dissipates the “store” left to each human.
