Banned US Athlete Makes Explosive Racism Claims Following Russia's Recent Doping Controversy

A huge racism storm has come to light following the decision to allow Russian athlete Kamila Valieva to continue competing at the Winter Olympics despite her failed drugs test.

Sha'Carri Richardson, who was barred from the Summer Games after testing positive to marijuana, claims she was treated differently to Valieva simply because of the colour of her skin.

She's calling it major double standards.

Russia, who have been no strangers to the odd PED in recent years, became embroiled in yet another doping scandal at this year's Winter Olympic Games in Beijing.

After clinching gold in the team figure skating event, the Russian's were preparing to collect their medals when the ceremony was cancelled right at the last minute.

It later came to everyone's attention that one of the Russian athletes had tested positive to a banned substance called trimetazidine which reportedly enhances endurance.

It was 15-year-old star Valieva.

After some deliberation, the Court of Arbitration for Sport along with the International Olympic Committee announced that Valieva would be allowed to continue competing in Beijing.

But rewind six months, and you'll see someone in a very similar situation get treated completely differently.

Unlike Valieva, American sprinter Richardson - who was favourite to win gold in the 100m event in Tokyo - was barred from the Games after a positive drugs test.

Now the 21-year-old is demanding answers.

"Can we get a solid answer on the difference of her situation and mine?" Richardson tweeted

"My mother died and I can't run and was also favoured to place top three.

"The only difference I see is I'm a black young lady."

Richardson's social media post has garnered a lot attention with over 115,000 likes and 27,000 retweets on Twitter alone.

The Court of Arbitration for Sport's controversial decision has been met with a barrage of criticism.

Winter Olympic spectators have flocked to social media to have their say on the matter, but perhaps the most damning assessment came from former Olympian-turned-Team USA figure skating coach Adam Rippon.

"Dirty cheaters, and we are accommodating them," he said.

"I don't know how the Olympics recovers from this.

"It's completely unprecedented that there would be an athlete with a positive test still competing, let alone competing at an Olympic Games. It just questions the entire integrity of the Olympic movement.

"What we're seeing now are the repercussions of no punishment, no action being truly taken."
