Pre-presidency: When he went on the Colbert Report for a segment about wanting to fly a cartoonishly large American flag at one of his golf courses but then had to admit that he didn't know what the 13 stripes represented. https://twitter.com/kept_simple/status/1351982539813097474
During his presidency:
Another moment https://www.washingtonpost.com/politics/2019/06/29/trumps-ignorance-basic-political-terms-is-full-display-overseas/
Other examples: Any of the times he claimed to have invented terms or coined phrases ("fake news," "priming the pump"), Boy Scout rally rant about sex on boats, when he said he tested positive for COVID before realizing that positive was bad so said "positively towards negative"
This moment
Oh, and then the time he had a fake movie trailer made where he and Kim Jong-un were action heroes
The time he said that he was building a border wall in Colorado, which does not share a border with either Mexico or Canada https://www.cnn.com/videos/politics/2019/10/24/trump-border-wall-colorado-daniel-dale-fact-check-ctn-vpx.cnn
Or when he wanted to nuke hurricanes https://www.axios.com/trump-nuclear-bombs-hurricanes-97231f38-2394-4120-a3fa-8c9cf0e3f51c.html

That's also the occasion that provided us with this image https://www.theguardian.com/us-news/2017/feb/13/mar-a-lago-north-korea-missile-crisis-trump-national-security
There was the time that he tweeted out what was almost certainly a classified photo (which wasn't illegal because technically, anything he shared would automatically become declassified because he was president) https://www.npr.org/2019/08/30/755994591/president-trump-tweets-sensitive-surveillance-image-of-iran
