In 2025, Murphy co-sponsored a bill alongside Pam Altendorf, to designate messenger RNA (mRNA) treatments, which include several COVID-19 vaccines, "weapons of mass destruction", and make possessing or administering them a crime punishable by up to 20 years in prison. The bill was drafted by a Florida-based hypnotist and conspiracy theorist who believes that mRNA treatments are "nanoparticle injections" that amount to "biological and technological weapons of mass destruction".
