The "Unmasking Hamas Act of 2025" proposes amendments to title 18 of the United States Code, aiming to enhance penalties for individuals who commit specific offenses while in disguise, particularly when wearing a mask. The bill's findings highlight concerns about violent student protests, property damage, and the use of masks to evade law enforcement, often linked to support for designated terrorist organizations and antisemitism on university campuses and public spaces. A key provision establishes a new section, 251, within chapter 13 of title 18, making it an offense to interfere with protected rights while in disguise . This includes injuring, oppressing, threatening, or intimidating any person in the free exercise of their constitutional or legal rights, carrying a penalty of fines, imprisonment for up to 15 years, or both. The bill explicitly states that this provision does not deter law enforcement officers from lawfully carrying out their duties. Additionally, the bill amends section 1363 of title 18, which pertains to destroying buildings or property within special maritime and territorial jurisdiction. It mandates an additional two-year term of imprisonment for anyone who wears a disguise, including a mask, during the commission of such an offense. This enhancement is applied in addition to any other imprisonment term already imposed for the underlying crime.
