Tesla chief executive Elon Musk, who helped fan the flames of the initial rally, replied to Ocasio-Cortez's tweet with: \"Absolutely.\"

Donald Trump Jr. also weighed in, calling the system \"rigged\" in a tweet.

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! #RobinHood #RedditArmy #GME #GMEtothemoon https://t.co/UhrwGHCjng

\"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,\" he wrote. \"This is what a rigged system looks like, folks!\"

Meanwhile, a lawsuit seeking class action status was filed Thursday against Robinhood in the Southern District of New York. A Robinhood spokesperson declined ABC News' request for comment on the suit.

Sen. Sherrod Brown, D-Ohio, the incoming chair of the Senate Banking and Housing Committee, said later Thursday that he planned to hold a hearing on the \"state of the stock market.\"

\"People on Wall Street only care about the rules when they’re the ones getting hurt,\" Brown said in a statement. \"American workers have known for years the Wall Street system is broken -- they’ve been paying the price.\"

People on Wall Street only care about the rules when they're the ones getting hurt.

It's time for SEC and Congress to make the economy work for everyone.

As Incoming Chairman of the @SenateBanking Committee, I will be holding a hearing on the current state of the stock market. https://t.co/V9Hzp26jRT

\"It’s time for SEC and Congress to make the economy work for everyone, not just Wall Street,\" Brown added.
