He was working the line inside of a manufacturing plant in Detroit and one of their employees challenged him on his gun stance Which got him a complete cussing out by Biden and a lot of finger-pointing right in his face. He also said something about taking away a r-14s. I really believe he's lost it. As much as people hate Trump this guy would be a disaster as the President of the United States. Everybody knows where I stand but I think it's fair to start examining Joe Biden's mental acuity.
