Senator Elizabeth Warren was the lead author of a letter signed by 28 other senators and 76 members of the House of Representatives about the role of cryptocurrency in financing terrorism. Signers came from both parties and included one independent, although Democrats predominate.
The letter, dated Oct. 17, was addressed to Treasury Under Secretary for Terrorism and Financial Intelligence Brian Nelson and National Security Advisor Jake Sullivan. The authors cited a news article that claimed Hamas and the Palestinian Islamic Jihad raised over $130 million in crypto donations between August 2021 and June 2023, and very little of the donated money had been recovered.
