WASHINGTON (AP) - Supreme Court Justice Ruth Bader Ginsburg is performing a same-sex wedding this weekend in what is believed to be a first for a member of the nation's highest court.
    
Ginsburg is officiating at the marriage of Kennedy Center President Michael Kaiser and John Roberts, a government economist, on Saturday. Kaiser says he asked Ginsburg to officiate because she is a longtime friend.
    
The private ceremony is taking place at the Kennedy Center for the Performing Arts, a memorial to President John F. Kennedy. The 80-year-old Ginsburg, an opera lover, is a frequent guest at the center.
    
Justices generally avoid taking stands on political issues. The wedding, though, comes after the court's landmark ruling in June to expand federal recognition of same-sex marriages, striking down part of an anti-gay marriage law.
