Billionaire Justin Sun sues Trump's crypto

The lawsuit, filed in a San Francisco federal court, claims that World Liberty Financial illegally blocked Sun from withdrawing his holdings after he declined to invest more capital.

Sun, a former ally of the president, asserts that the company secretly installed software to prevent the sale of his tokens.

World Liberty Financial has not yet issued a formal response to the allegations of fraud and criminal extortion.

The legal battle marks a significant rift between the Trump family's business interests and one of its most prominent early supporters in the blockchain space.
