Billionaire backer sues Trump family's crypto firm over alleged extortion

Sun is an ardent supporter of Trump and his stance on cryptocurrencies, but accused "certain individuals" associated with World Liberty of acting against the president's values.

"They wrongfully froze all of my tokens, stripped me of my right to vote on governance proposals, and have threatened to permanently destroy my tokens by 'burning' them - all without any proper justification," he said in a social media post announcing the lawsuit.
