Not saying it’s not an internet meme, but NBC News seems to have ran the quote yesterday, and hasn’t updated the article with a correction:

he Biden campaign slammed the former president in a statement about the expected gun license revocation.

“When Trump tells the NRA he won’t do a damn thing to prevent convicted felons, domestic abusers, and other dangerous people from getting their hands on guns, he’s talking about himself,” said campaign spokesperson James Singer in a statement.

I checked James Singer’s twitter and couldn’t find a written statement, nor a rebuttal to NBC News article, so maybe this was a spoken quote off the cuff?
