The Supreme Court could issue a ruling on abortion as soon as Monday, which would be days after a memo leaked from the Department of Homeland Security (DHS) reveals the Biden administration is preparing for a nationwide wave of violence following the decision on the future of Roe v. Wade.

A leaked draft opinion by Justice Samuel Alito signaling the high court plans to overturn landmark abortion case Roe v. Wade sparked pro-choice protests nationwide and an uptick in violence. Protesters have targeted the homes of conservative Supreme Court justices and vandals have targeted at least five pro-life crisis pregnancy centers across the U.S. and Catholic churches have been threatened and vandalized.

Additionally, a memo dated May 13 from DHS reveals that the Biden administration is investigating threats to the Supreme Court building and to justices in the weeks since the leak. The memo first reported by Axios details ongoing investigations into threats to “burn down or storm” the Supreme Court building.

In addition, the DHS memo reportedly says the protests outside conservative justices’ homes “are likely to persist and may increase leading up to and following the issuing of the Court’s official ruling.”
