The nation paused to honor Jimmy Carter for his service as a naval officer, governor and president, and his four decades of humanitarian work after leaving the White House.

At a pomp-filled state funeral, mourners paid tribute to Mr. Carter and argued that he was a more successful leader than many remember. “It’s time to redeem his presidency,” a former aide said.

Jimmy Carter, the late U.S. president who served only one term in office and was widely admired for his humanitarian work after leaving the White House, was remembered during his state funeral on Thursday as a man who put honesty and kindness above partisan politics.
