World Liberty Financial, the cryptocurrency venture linked to former President Donald Trump, has filed a defamation lawsuit against Justin Sun, the billionaire founder of the TRON blockchain. The project claims Sun launched a coordinated media campaign designed to damage its reputation after he sued the Trump-linked venture last month.

Sun, who previously faced SEC charges for securities fraud, initiated the original legal action against World Liberty in December. The new defamation suit marks a significant escalation in the dispute between two major figures in the crypto industry. World Liberty alleges Sun's public statements and media outreach were part of a deliberate effort to harm the project's standing with investors and the broader public.

The legal battle underscores the increasingly contentious nature of disputes among high-profile crypto entrepreneurs. World Liberty, which launched its token earlier this year with direct involvement from Trump family members, has faced scrutiny since its debut. The countersuit signals the project is prepared to mount an aggressive defense against critics.
