Donald Trump, apparently noticing the elevation of Democrat Pete Buttigieg into the presidential conversation for 2028, tried to take down the former transportation secretary with a much-mocked attack in Doha, Qatar, on Thursday. (Watch the video below.)

“He goes bicycling to work,” Trump said. “He takes a bicycle to work. Can you believe — he’s running the biggest air system in the world, and he takes a bicycle to work. What a— and they say he’s going to run for president. I don’t see it.”

“Laughable,” one commenter wrote. “Especially from someone who can’t even walk 700 yards without a golf cart. Hypocrisy at its finest, attacking exercise while claiming to make America healthy again. Pathetic.”

“Jealous? When was your obese ass last on a bike?” another asked of the president.

One person on X put Trump’s misguided attempt at an insult into strictly political terms, writing:

“Trump is scared of Pete Buttigieg.”

This isn’t Trump’s first remark on Buttigieg biking, either. He brought it up recently, saying that Buttigieg has been seen riding a bike with his husband “on the back.”

Buttigieg, who ran for president in the 2020 election, made an impressive appearance in Iowa this week. He sounded like he was ready to try again while giving an anti-Trump message.

As a counterpoint to Buttigieg, Trump at one point launched into a bizarre word salad about the former lumberjack sports career of Transportation Secretary Sean Duffy.

Duffy has come under fire for increasing concerns over airport safety amid malfunctions at Newark Liberty International Airport and high-profile aircraft crashes elsewhere.

Trump showed his support for Duffy by touting his ability to climb trees.
