The city of Harrisburg, Pa., is pushing back against Donald Trump's "disparaging" description of the capital city as looking "like a war zone."

The GOP presidential nominee made the comparison at a rally in Virginia on Tuesday, the Daily Beast reports.

Telling the Virginia rally that he'd recently flown over Harrisburg in his private plane, Trump said it "looked like a war zone where you [once had] these massive plants," the Daily Beast reports.

The city's director of communications, Joyce Davis, took the remark as an insult.

"Mr. Trump has made an unfortunate mistake in disparaging Pennsylvania’s capital city after a mere glance from the window of his airplane," she writes in an email, the Daily Beast reports.

"Mr. Trump should know that Harrisburg and its residents are an integral part of the United States, which he is vying to lead. Its rich history and natural beauty have won both the respect and acclaim of some of America’s greatest leaders and patriots."

The Keystone State, with its 20 electoral votes, is, along with Florida and Ohio, one of three battleground states that could deliver enough electoral votes to "tip" the November contest to Trump, according to an analysis by the New York Times.

Trump won the state's primary in April.
