Democratic presidential candidate and former Vice President Joe Biden argued with a Detroit autoworker after the latter accused Biden of “actively trying to end our Second Amendment rights.”

“You’re full of s--t,” Biden told the autoworker Tuesday during a tour of the Fiat Chrysler auto plant on Michigan’s primary voting day. “I support the Second Amendment.”

Biden said he’s in favor of gun rights, but believes there are limits to the Second Amendment, such as how the First Amendment right to speech doesn’t allow people to irresponsibly yell “fire!” in a crowded theater.

“I have a 20-gauge, 12-gauge. My sons hunt," Biden said. “I’m not taking your gun away at all.”

The autoworker claimed he saw a “viral video” where Biden allegedly called for a ban on guns.

“I did not say that,” Biden said. “It’s like the other viral videos they’re putting out that’s a lie.”

Biden has been the subject of several misleading videos on social media. President Donald Trump shared a deceptively edited video suggesting Biden endorsed Trump this past weekend, removing the second part of a sentence about negative attacks against fellow Democratic candidates: “We can only re-elect Donald Trump if in fact we get engaged in this circular firing squad here. It’s gotta be a positive campaign.”

USA Today reports another video shows Biden speaking with former Rep. Beto O’Rourke, who supports a mandatory buyback program, and admiring his positions on assault weapons and climate change. Biden tells O’Rourke’s wife that if he wins the election he is “coming for him,” potentially for a job in his administration, but some conservative sites have falsely claimed Biden said “I’m coming for them," meaning guns.

Biden told the autoworker he doesn’t want to confiscate guns, but argued AR-15s -- which he mistakenly referred to as “AR-14s” -- should be illegal like machine guns.

"You need 100 rounds?” Biden said.

“You’re working for me, man,” the worker later says in the exchange.

“I’m not working for you,” Biden said. “Give me a break, man. Don’t be such a horse’s a--.”

According to Biden’s website, he favors a ban on the sale and manufacture of assault rifles and high-capacity magazines; those who currently own them would be able to sell them as part of a voluntary government buyback program, or register them with the Bureau of Alcohol, Tobacco, Firearms and Explosives. He also supports expanded background checks, “red flag laws” to keep guns away from people with mental illnesses and limits on how many guns people can buy.

Biden was in Detroit campaigning for Michigan’s presidential primary, which he went on to win Tuesday night.

“Just a few weeks ago, many of the pundits had declared this candidacy dead. Now we’re very much alive," Biden said.
