US Supreme Court Justice Amy Coney Barrett told lawmakers Tuesday that a sharp increase in threats targeting her and other justices is increasingly encroaching on their personal and family lives.During a rare appearance by justices before Congress, Barrett said she had to take a bulletproof vest home a few years ago, something she struggled to explain to her 12-year-old son.“I didn’t expect that performing this service would put me in the position of explaining to my children what a bulletproof vest was, why I had to wear one,” she said.She and Justice Elena Kagan testified before appropriations panels in the House and Senate in support of a request to increase security funding for members of the nation’s highest court.Judges around the country have seen a rise in threats of violence and intimidation, including fake emergency number calls to trigger police raids and pizza deliveries in the name of a judge’s murdered son.US Supreme Court Justices Elena Kagan (left) and Amy Coney Barrett testify during a Senate Appropriations Subcommittee on Financial Services hearing on Capitol Hill on Tuesday.
