Billionaire Justin Sun Sues Trump Firm

The legal battle marks a dramatic falling out between the Trump family's crypto project and one of its most prominent early supporters.

Sun claims that World Liberty Financial secretly installed tools to prevent him from selling his tokens after they became tradable last September.

The lawsuit, filed in federal court, also accuses a co-founder of the project of attempting to extort more money from Sun before blocking his withdrawals.

The case has raised fresh questions about the transparency and security of the President's financial ventures as they face increasing regulatory scrutiny.
