US Supreme Court Justice Antonin Scalia's memorial service has provided a brief respite for official Washington from the fierce battle over his succession, with political and legal leaders and many others in attendance.
At the blue-domed Basilica of the National Shrine of the Immaculate Conception, the nation's largest Catholic church, dozens of priests took part in Saturday's funeral mass, led by one of the justice's nine children, Reverend Paul Scalia.
More than 3000 people looked on, including other family members, the court's remaining eight justices, lawmakers, Vice President Joseph Biden and former Vice President Dick Cheney.
"God blessed Dad with a deep Catholic faith," the younger Scalia told the gathering inside the cathedral. "He loved the clarity and coherence of the church's teachings."
He fondly remembered an outburst one day after his father realised he was waiting for confession at church in a line that would have led him to his son. The justice jumped out of the line.
"'Like heck if I'm confessing to you,'" the father said later to the son, who remarked: "The feeling was mutual."
A staunch conservative and the court's longest-serving member, Justice Scalia died last Saturday at age 79 at a Texas hunting resort, sparking a political struggle that promises to reshape the 2016 election campaigns.
Presidential candidate Ted Cruz, a Republican senator from Texas, was among those at the service. Like other Republicans, he has said that US President Barack Obama, a Democrat, should not choose Scalia's replacement.
Rather, Republicans are saying no one should be named until after the presidential election in November, hoping that one of their own will be elected and get to choose the next justice.
Under law, the US president is responsible for nominating Supreme Court justices to their lifetime appointments, subject to Senate review and confirmation.
Appointing a justice to the court is one of the biggest decisions a US president can make.
Obama has vowed to select a successor to Scalia.
