The ceremony has taken on added significance, coming a day after the anniversary of the January 6, 2021, Capitol riot, in which Donald Trump’s supporters stormed the building in an attempt to block certification of Joe Biden’s election victory.
On Monday, Congress certified Trump’s win over Harris without any disruptions and with the complex under very heavy security.
A state funeral service is to be held Thursday at the National Cathedral, an Episcopal church in Washington that also hosted funerals for former presidents Dwight Eisenhower, Ronald Reagan, Gerald Ford and George H.W. Bush.
Current President Joe Biden is to deliver the eulogy for his fellow Democrat.
All four living former presidents — Bill Clinton, George W. Bush, Barack Obama and Trump — are expected to attend.
