Democratic frontrunner “Sleepy Joe” Biden shouted profanities against a hard hater when asked about his previous gun-control remarks in a visit to an auto plant on Tuesday.

As Biden walked through the crowded Fiat-Chrysler plant, a construction worker asked him whether the former vice president plans to take away both the American right to the second Amendment, as well as their guns.

Instead of clarifying his previous comments, Biden simply shot back, “You’re full of sh**t.”

The presidential hopeful continued to say that he supports the Second Amendment, linking it incoherently to someone’s freedom of speech. Biden himself admitted to owning a 20-gauge, and 12-gauge before he continued to slur the words and concluded that “I’m not taking your gun away at all.”

Biden flatly denied that he did not make such comments. However, the worker cited a viral video in which the former vice-president, as well as former Texas Congressman and gun-control activist Beto O’Rourke, made remarks about gun confiscation. “I did not say that. That’s not true. I did not say that,” the former vice president insisted.

“Wait, wait, wait,” Biden interrupted. Then, things started to escalate as the presidential hopeful pointed a finger on the worker’s chest, declaring that he is going to take away the AR-14s (although no such weapon exists and that Biden might be referring to AR-15s).

The man responded, saying that it was not okay, to which gaffe ridden Biden challenged him into a fistfight, “Don’t try me, pal…Do you want to go outside?” while other onlookers tried to get in the way. The worker reminded Biden, “You’re working for me, man.”

The former vice president called the worker a “horse’s ass” and declared that he was not working.

Watch:

For years, Biden had been an outspoken gun-control activist. Along with O’Rourke, who had publicly endorsed him for the Democratic primaries, Biden supported the ban on sale and manufacture of “assault weapons.” His proposed mandatory buyback policy includes either selling or giving back the guns to the government, as well as with other weapons such as machine guns and silencers.

Biden had, in fact, announced that O’Rourke would be helping him to implement stricter gun-control policies saying that the congressman will “take care of the gun problem with me.”

This is not the first time that Biden had engaged in a heated confrontation with voters. Just last month, the former vice-president called Madison Moore, a college student at Mercer University, a “lying, dog-faced, pony soldier” after she asked him why he was not doing well in the presidential race. In an interview, Moore echoed the same sentiment that Democratic insiders have had, questioning if Joe Biden is truly capable of being the next commander in chief. Moore spoke publicly about the incident and described it as a form of “bullying.”

In another instance, Biden also called an Iowa voter a “damn liar” when asked about allegations of corruption against his son Hunter.
