Brothers Michael and Gerald Shvartsman pleaded guilty to an insider trading scheme related to Donald Trump's social media company merger. They profited over $23 million by tipping off friends about the planned merger of Trump Media & Technology Group and Digital World Acquisition Corp. Michael was seen as the mastermind, and with his $18.2 million in illegal profits, he bought a $14 million yacht. Gerald made $4.6 million illegally from the scheme. Trump's company went public last week, but shares have been volatile.
