Reddit’s WallStreetBets GameStop campaign, Robinhood crackdown brings Alexandria Ocasio-Cortez, Donald Trump Jr together

The rapid rise of GameStop stock and the subsequent decision by a market application to crack down on trading by retail investors has brought together two figures from the polar opposite ends of the political spectrum.

Bolstered by groups of small-time investors on internet forums like Reddit, GameStop's stocks have been pushed sky-high recently, angering hedge fund managers who had bet the companies' shares would fall.

The massive jump in GameStop stock - up 2000 percent since the start of the year - started after users on the Reddit page WallStreetBets decided to join together in purchasing shares for the game shop which has struggled as the world moved into a more digital space. 

Robinhood, an application that promotes "investing for everyone", on Friday restricted trading on the GameStop shares as well as for other companies in similarly perilous financial situations, such as cinema chain AMC. It said the decision was made "in light of recent volatility" and that it was "important as ever [to] help customers stay informed".

Social media users have noticed that two political figures normally on completely different sides of the aisle have come to the support of the retail investors and the decision to stamp down on trading. 

Democrat Alexandria Ocasio-Cortez tweeted on Thursday that "it's really something to see Wall Streeters with a long history of treating our economy as a casino complain about a message board of posters also treating the market as a casino".

Meanwhile, Donald Trump Jr, the son of former US President Donald Trump, shared several tweets about Robinhood's decision. 

"Somebody is going to have to explain to me in what world @RobinhoodApp and others literally trying to force a crash by closing the open market is fair? They should all be in jail," one person said on Twitter.

Trump Jr shared that tweet, saying: "It took less than a day for big tech, big government and the corporate media to spring into action and begin colluding to protect their hedge fund buddies on Wall Street. This is what a rigged system looks like, folks!"

He also called for Republicans to launch an investigation into Robinhood - something Ocasio-Cortez also appears to support.

"This is unacceptable. We now need to know more about @RobinhoodApp's decision to block retail investors from purchasing stock while hedge funds are freely able to trade the stock as they see fit. As a member of the Financial Services Cmte, I'd support a hearing if necessary."

Since trading restrictions came into effect, the stock has plunged by about 40 percent. It's still significantly up on a few weeks ago.
