Reports indicate heightened security for judges due to increased threats, particularly those involved with Trump administration cases.

The U.S. Supreme Court did not comment on the incident, and security concerns have been raised for judges amid increasing threats.

Williams' husband, David, mentioned that a pizza delivery made on the same evening might be related to the threat, amidst concerns of intimidation tactics used against federal judges.

Justice Barrett, appointed in 2020 by President Donald Trump, has faced criticism from some of Trump's supporters following a recent ruling on foreign aid payments.

Before her appointment, Barrett served on the U.S. Court of Appeals for the Seventh Circuit and was a law professor at Notre Dame.

The FBI's Columbia field office assisted local police in the investigation of the threat.

Barrett previously mentioned feeling the need for a bulletproof vest after receiving threats, indicating ongoing concerns for her safety.

Amanda Coney Williams, the sister of U.S. Supreme Court Justice Amy Coney Barrett, received a bomb threat at her home in Charleston, South Carolina, earlier in March 2025.

The email included political language, stating 'Free Palestine,' and as of now, no arrests have been made, with the investigation ongoing.

This incident is part of a broader trend, as Chief Justice John Roberts has highlighted an increase in threats against the judiciary, including recent cases involving threats against other justices.

The Charleston police responded to the threat after an email was sent detailing a homemade bomb placed in Williams' mailbox, but it was later determined to be a false alarm after inspection.

The Federal Judges Association expressed concern over the intimidation and threats facing the judiciary, highlighting the bomb threat against Barrett's sister as a serious issue.
