The Washington Post fact-checker Glenn Kessler has given President Joe Biden the maximum Four Pinocchios for his false claims on the 2nd Amendment–specifically cannon ownership–in remarks to the press recently.
“And I might add: The Second Amendment, from the day it was passed, limited the type of people who could own a gun and what type of weapon you could own. You couldn’t buy a cannon.”

Kessler consulted experts on the 2nd Amendment who agreed that the 2nd Amendment which states that “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed,” has been mischaracterized by Biden.
The experts told Kessler that Biden is suggesting that the 2nd Amendment limited ownership which it clearly does not do.
Kessler found the canon reference particularly intriguing, especially since Biden had mentioned it before and was wrong that time too.
During the presidential campaign, Biden had asserted that the cannon restrictions happened during the Revolutionary War. “From the very beginning you weren’t allowed to have certain weapons,” Biden told Wired magazine  in May 2020. “You weren’t allowed to own a cannon during the Revolutionary War as an individual.”’
“Historians at the time told PolitiFact  there was no evidence this was the case. The Biden campaign could not point to any laws but seemed to suggest Biden’s point was more metaphorical than grounded in reality.”
“Some readers might think this is a relatively inconsequential flub. But we disagree. Every U.S. president has a responsibility to get American history correct, especially when he’s using a supposed history lesson in service of a political objective. The president’s push for more gun restrictions is an important part of his political platform, so he undercuts his cause when he cites faux facts.”
“Moreover, Biden has already been fact-checked on this claim — and it’s been deemed false. We have no idea where he conjured up this notion about a ban on cannon ownership in the early days of the Republic, but he needs to stop making this claim.”
