Is there any excuse for Trump claiming that, in 1776, "...Our army ...took over the airports..."?

To be honest, the first time I heard this, yesterday, I assumed it was a hoax. No one could be THAT stupid. Turns out, he really made this claim. So what excuse do you give him? And what excuse is there for the other inaccuracies that any high school graduate would not have made?

The Post said ”There were inaccuracies like this peppered throughout the speech ⁠— the president still seems to not know exactly who “Douglass, Frederick Douglass, the great Frederick Douglass” is ⁠— but Trump was especially befuddled when he described the creation of the U.S. Army.”

Also, “First, it’s clear the president was having some issues reading the teleprompter, which led to a number of errors. For example, British General Cornwallis was of London; he was defeated at Yorktown. The Continental Army wasn’t named after Washington; it’s possible Trump substituted “named” for a different verb in the text of the speech.”
