Trump Media surged in the first day of trading following an assassination attempt on former President Donald Trump.

Also on Monday, a federal judge presiding over Trump's classified documents trial in Florida dismissed the case because of her concerns over the appointment of the special prosecutor who brought the case.

Shares in the owner of social networking site Truth Social soared more than 35% in early trading.

The U.S. Secret Service is investigating how a gunman armed with an AR-style rifle was able to get on a nearby roof and shoot and injure the former president at a rally Saturday in Pennsylvania.

The gunman, who officials said was killed by the Secret Service, fired multiple shots at the stage from an "elevated position outside of the rally venue," the agency said. Trump was bloodied and says he was "shot with a bullet that pierced the upper part of my right ear." A spectator was killed.

The stock frequently makes double-digit percentage moves either higher or lower in a single day. It peaked at nearly $80 in intraday trading on March 26. For context, the S&P 500 is up 18% year to date.

Trump Media reported in May that it lost more than $300 million last quarter, according to its first earnings report as a publicly traded company.
