Two U.S. senators have called for a probe into alleged links between North Korean cybercriminals and a cryptocurrency firm tied to President Donald Trump’s family, raising security concerns about the sale of virtual tokens to actors connected to Washington’s “enemies.”

In a letter to Treasury Secretary Scott Bessent and Attorney General Pam Bondi on Tuesday, Sens. Elizabeth Warren and Jack Reed of the Democratic Party sought information on an investigation into reports that the Trump family-backed World Liberty Financial (WLF) sold virtual currency tokens to buyers linked to the DPRK and other illicit actors.
