This bill creates a new federal crime targeting the transportation of minors across state lines to receive gender-related medical procedures. Specifically, it makes it illegal to knowingly transport a minor in interstate or foreign commerce for the purpose of obtaining puberty blockers, hormone therapy, or gender-affirming surgeries. The bill treats this as a serious federal offense punishable by up to 10 years in prison and fines. The bill also allows minors or their parents to sue in federal court for damages if they believe someone has violated this law. Additionally, the legislation includes a financial penalty: states and local governments that enact policies permitting minors to travel across state lines for these procedures, declare themselves 'sanctuary jurisdictions' for such procedures, or fail to cooperate with federal investigations could lose federal funding. The bill's sponsors argue that these medical procedures are experimental and potentially harmful to minors, and that the federal government has an interest in regulating interstate travel for these purposes.
