The Trumps' World Liberty Financial project has frozen WLFI tokens in wallet addresses belonging to Justin Sun that contain ~$100 million (on paper) in unlocked WLFI. Sun is a major backer of the project, which the Trumps say they founded to stop "debanking".
The freeze apparently came after Sun transferred around ~$9M of his holdings to Binance.
The World Liberty team has been desperately trying to prevent the WLFI price from sinking, including by burning tokens to boost the price. They may be concerned that whales like Sun could further depress the token price by cashing out.
