In this photo released by The White House, former President Jimmy Carter, center left, and former first lady Rosalynn Carter, center right, pose for a photo with President Joe Biden, right, and first lady Jill Biden at the home of the Carter's in Plains Ga., April 30, 2021. Former President Donald Trump is running against Biden, but Trump, the presumptive Republican nominee, keeps bringing up Carter. Trump likes to cite the 99-year-old former president as a measuring stick to belittle Biden. (Adam Schultz, The White House via AP)
