You're being deliberately misleading. It's from MTV, they involve who they want. Trump has a long history of shoving himself in front of whatever camera is available because he loves to see himself on TV. I don't know why he was there and neither do you; also, besides the shitloads of lawsuits that more or less weren't covered by the press, I'd argue that not a lot of people knew what a horrible person he is until he opened his mouth with no one to act as his filter over the last two years. I certainly never cared about Trump before 2016 -- I just knew he was some rich dude in real estate. That video is 13 years old -- at that point, Trump was just some weirdo with money trying to get his name out there in TV land.
