(TNS) — Donald Trump had his lengthy conversation with Elon Musk on X on Monday, and one thing that could not be missed through it all was the former president’s slurred speech.

Trump often sounded as though he was speaking with a heavy lisp or slurring his words, and that had social media stirring.

Some folks mocked Trump for his speech. Some worried about what might be going on with him, and wondered if it was a physical issue. Others tried to explain how technical issues could have caused the sound.

Lou Holtz, the famous former Notre Dame coach who has a pronounced lisp, trended on X following the interview as folks compared Trump’s speech to his.

Kamala Harris’ campaign certainly took notice, reposting a clip from the sit down and writing, “Trump, slurring, says he’s okay with climate change and rising sea levels because he thinks he’ll ‘have more oceanfront property.’”

“BREAKING: Reporters are calling out Donald Trump for his slurring of words tonight,” the X account, Kamala’s Wins, posted. “It’s clear to the American people that Donald Trump is not cognitively or physically well enough to be President of the United States.”

“Not a joke here: Trump is really badly slurring his words,” Rex Huppke wrote. “This is quite disturbing. Something is wrong with him.”

“This is some of the worst slurring I’ve ever heard,” the Acyn account posted. “Trump appeared to be in steep cognitive decline when speaking to Elon.”

“Did Trump have a small stroke,” BobbyV posted on X. “he’s slurring and lisping during his X interview with Musk. He better figure that out before any national debate.”

Trump did not offer an explanation on social media as of early Tuesday morning, but there were others who came to his defense.

“For all of you that are talking about Trump slurring it’s because his head is down and it cuts off some of your windpipe and causes you to sound like that,” the Ultra Force PATRIOTS account on X wrote. “Try it on yourself and see if you sound the same. Trump is fine and doing a fantastic job knock it off.”

“So let’s be clear, whatever made Trump sound off on tonight’s space, was due to the microphone, bc here, on another recording device, he sounds normal,” Aaron Newborn wrote on X.

Trump has surely seen the speculation, and it is rare that he does not respond to such things, so it will be interesting to see what his explanation is for the odd sound.
