Critics of President Donald Trump were flying high Thursday after his jaw-dropping gaffe in his Independence Day speech, in which he said that the brave U.S. Army took over airports during the Revolutionary War.

Trump, clearly reading from a teleprompter, talked about how the Continental Congress in 1775 “created a unified Army out of the Revolutionary Forces encamped around Boston and New York.” The army suffered a “bitter winter of Valley Forge, found glory across the waters of the Delaware and seized victory from Cornwallis of Yorktown,” Trump said. General Cornwallis, of London, was defeated at Yorktown.

Here’s where it goes off the rails: “Our Army manned the air, it rammed the ramparts, it took over airports, it did everything it had to do,” Trump added. “And at Fort McHenry, under the rockets’ red glare, had nothing but victory. When dawn came, the star-spangled banner waved defiant.”
