Harrisburg officials said Donald Trump made "an unfortunate mistake" when he insulted the city Tuesday afternoon.

During a campaign stop in Ashburn, Virginia, the GOP presidential nominee said Harrisburg "looked like a war zone" from the window of his plane.

He made the comments just before noon and less than 24 hours after he stumped in central Pennsylvania.

"Mr. Trump has made an unfortunate mistake in disparaging Pennsylvania's capital city after a mere glance from the window of his airplane," city spokeswoman Joyce Davis said in a statement, according to Politico. "Harrisburg is renowned as the heart of our commonwealth and a capital of unique beauty and charm. Mr. Trump should know that Harrisburg and its residents are an integral part of the United States, which he is vying to lead."
