Donald Trump on Saturday shouted out North Carolina from the stage while speaking at his rally in Pennsylvania, leading some observers to ask if the former president simply forgot where he was.

Trump, who earlier in the speech admitted to going “off teleprompter” to insult his former political foe, Joe Biden, was talking about how long his speeches are when he made the possible error. He was specifically noting that people demand he speak more than Biden.

“They have a tent, and the tent is set up. They have hundreds of them, and they wait,” Trump said.

“And then I walk in, and speak for 15 minutes, and leave. I don’t know… Would that be ok, North Carolina?” Trump asked the attendees of his rally located in Wilkes-Barre, Pennsylvania.

The backlash online came instantly.

Vice President Kamala Harris’ campaign quoted Trump as saying, “Would that be okay, North Carolina?” and then added simply, “He is in Pennsylvania.”

Republican Voters against Trump said, “Trump doesn’t know what state he’s in.”

“He just asked the crowd at his Pennsylvania rally, ‘…would that be okay, North Carolina?’ Trump is the oldest candidate for President,” the group added.

Harris spokesman Sarafina Chitika also chimed in: “Once again asking: is [Trump] ok?”

MSNBC executive producer Kyle Griffin said, “Trump confuses the state he’s in — shouting out North Carolina when he’s in Pennsylvania.”

One reporter had an alternate take. Julia Manchester of The Hill wrote, “Trump did not confuse Pennsylvania and North Carolina here.”

“He is addressing a group of supporters from North Carolina who are at his rally in Pennsylvania. Before this clip he says ‘I have another group from North Carolina. We love North Carolina,'” she added.
