I was watching the Weightlifting on the BBC there and one of the presenters stated that Weightlifting may be removed from the Olympic Games due to Doping Scandals in the lead up to the 2020 Games. Several countries were banned from competing because of the doping issues.

It's crazy to think that such an important and popular event at the Olympic Games may be cancelled given the history of the sport. Here's an article online describing the problem with Olympic Weightlifting.
I'm not really sure whether I believe there are any "clean" athletes at the Olympic Games. To compete at such a high level, it's a bit naive to think athletes are winning by not taking performance enhancing drugs.
