"We have an obligation to give hate no safe harbor," the president asserted with Donald Trump in the audience.

President Joe Biden was in his first term as senator for Delaware in 1977 at the time Carter was in office. Biden will be at Carter’s funeral Thursday morning to give a eulogy to the late 39th president.

All five living presidents will be present to honor the late former President Jimmy Carter during his funeral service at the National Cathedral in Washington, D.C. on Thursday morning.

President Joe Biden spoke of his friendship with Jimmy Carter that started in 1974 when Biden was the first sitting Democratic senator to endorse the late president.

Trump is obviously no fan of Biden, but Obama and his veep also have a famously complex relationship, only made more so after Obama helped nudge Biden to quit the presidential race last summer. Surely Obama feels some frustration that Biden fumbled a possibly winnable race; maybe he couldn’t help spill to his sworn enemy?

One of the first calls Obama made after U.S. forces killed Osama bin Laden in 2011 was to George W. Bush to spread the word that the mission had been accomplished, said Kate Andersen Brower, author of “Team of Five: The Presidents Club in the Age of Trump.”
