A bill which would have made female genital mutilation (including a vacation cutting clause) a first degree felony in the State of Pennsylvania passed unanimously in the House of Representatives, but failed when the Senate adjourned for the year without taking action.
The bill will likely pass next year and be signed into law, making Pennsylvania the 28th State to outlaw FGM.
The (correct) decision to strike down the Federal statute gives new urgency to State by State passage of statutes and I think all States can and should enact bills into law before the end of 2019.
The Federal statute still stands as law in the District of Columbia, the territories, military bases and other places under exclusive Federal jurisdiction, just not in the States.
It is relatively rare, but any incidence at all is one incidence too many. While it likely could be handled under existing child abuse/child endangerment laws, an FGM statute is a relatively trivial matter to pass.
