In 2022, Nicholas John Roske was accused of trying to assassinate Supreme Court Justice Brett Kavanaugh. He was arrested with weapons near Kavanaugh's house soon after a draft opinion in the case striking down Roe v. Wade was leaked. Roske has pleaded not guilty.

After that incident, Congress passed a law to provide 24-hour security for the families of Supreme Court justices. The justices themselves were provided with 24-hour protection by the U.S. Marshals soon after the leak of the opinion.
