He most likely meant ports.... The ones in all 57 states.

He was looking at the teleprompter during that part of the speech, and yes, and it most likely said "ports" and he misread it. However, the same sentence also mentioned the Battle of Fort McHenry which was the War of 1812, so it's certainly possible that the speech writer/teleprompter actually had the word airport. It was an hour-long speech, and like anyone giving a long speech, he's relying on a teleprompter as nobody can commit a speech of that length to memory--especially since it likely wasn't finalized until that day, and he has more important things to do than spend the majority of the day rehearsing a speech to commit it to memory. It was one very minor misstatement in an otherwise fact-intensive and historically relevant speech that was well delivered.
It's sad, but not unexpected, that the deranged leftists pour over every word of his speeches looking for the slightest mistake so they can turn it into the main talking point for the next 48 hours. And it's particularly sad and petty that they do it in an effort to undermine the importance of the underlying message in speeches marking events that were historically monumental for freedom and liberty, like the 75th Anniversary of D-Day, and the birthday of our nation's independence from tyranny and oppression.
