The panel on MSNBC's "Morning Joe" suggested Thursday that President Trump is suffering from diminished mental capacity after he delivered a speech and slurred some of his words toward the end.

Republican strategist and MSNBC contributor Steve Schmidt, a regular on the show, said Trump appeared to have an "impairment" and called it "chilling" to watch.

"This is not the person that we knew even three years ago. ... There’s a remarkable change," said host Joe Scarborough.

"He seemed like he was almost hanging on to the prompter and hanging on to the words," co-host Mika Brzezinski said. "Something, I don’t know. ... There was a struggle happening."

Trump delivered remarks the previous day from the White House on his announcement to recognize Jerusalem as Israel's official capital. At the end, his tongue appeared to get stuck on certain words, causing him to slur parts of the speech.

The Daily Beast columnist Mike Barnicle said on "Morning Joe" that stress and poor physical condition may have been the cause.

"When you consider his age, his physical condition, he does not look in great physical shape and hasn’t for some time," he said. "The anxiety, the worry, the burden of knowing that Bob Mueller and the special prosecutor is out there investigating nearly every aspect of his life and his family’s financial life and the fact that you know, he doesn’t really know the mechanics, the nuts and bolts of what he’s talking about a lot of times."

Scarborough said his own mother suffered from dementia, and suggested Trump might have the same problem.

A similar episode with Trump happened three weeks ago when he returned from a tour of Asia and spoke at the White House about the trip's success.

Trump also began to slur then, so he reached for a drink of water.
