President Joe Biden, former presidents and other dignitaries are gathering at Washington National Cathedral in Washington, D.C., to honor former President Jimmy Carter.

Carter's remains will be taken to the Washington National Cathedral after lying in state at the Capitol this week. Following the service, his remains will be taken to Carter's hometown of Plains, Georgia for a private funeral service and interment Thursday night.

In a rare show of unity in these tumultuous times, every living American president filed into pews together Thursday to honor one of their own at the funeral for President Jimmy Carter at the Washington National Cathedral on Thursday.
