President Joe Biden delivered remarks on Tuesday at gun control advocacy group Everytown’s annual conference, Gun Sense University — and as is often the case when Biden speaks about guns, critics were quick to point out a series of factual errors.

Biden’s comments, which came within hours of his embattled son Hunter Biden’s conviction on several gun-related felonies, included a few of his oft-repeated — and already debunked — claims, in addition to a few new additions.

Greg Price noted several mistakes that Biden whipped through in under a minute — from debunked claims about his alleged history as a professor to the assertion that the Second Amendment was written in a time when individuals were not permitted to own cannons.

“Joe Biden in less than a minute,” Price began, adding, “Claims he was a professor at Penn, which he never was; Claims he taught a constitutional law class on the second amendment, which he never did; Says that you couldn’t own a cannon when 2A was implemented, which you could; And ends by failing miserably to say the phrase ‘the tree of liberty is watered with the blood of patriots.'”

Joe Biden in less than a minute:

– Claims he taught a constitutional law class on the second amendment, which he never did
– Says that you couldn’t own a cannon when 2A was implemented, which you could

“There has never been a time that says you could own anything you want. Never. You couldn’t own a cannon during the Civil War. No, I’m serious. Think about it,” Biden said — but as the New York Post reported, the few laws passed regarding cannons during the 19th century were primarily focused on “limiting where they could be discharged, restricting the sale of the weapon to children and regulating how gunpowder could be stored.”

It is still legal to own Civil War era cannons in the United States.

And as for the late President Thomas Jefferson’s quote — “The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants” — Biden’s version was as follows: “How much have you heard this phrase, ‘the blood of liberty … washes those’ – give me a break.”

GunOwners of America added a few more infractions to Price’s list:

“Oh don’t forget @JoeBiden also: Said Americans would need F-15s to resist his tyrannical government (You wouldn’t); Claimed the firearm industry is the only industry with immunity (They aren’t); Claimed that guns kill more children than car accidents and cancer combined (They don’t); Got the name of the federal agency responsible for gun control wrong (AFT).”

Biden also repeated his call to ban “assault weapons,” saying that he did not understand who needed a magazine that could “hold 200 shells.”

Biden (again) calls for a ban on “assault weapons,” which he later calls “weapons of war.”

As Biden spoke, he was briefly interrupted by a pro-Palestinian protester who accused him of being “complicit in a genocide” because he has continued to support Israel in its ongoing war against Hamas terrorists.
