President Joe Biden celebrated his 81st birthday by joking about his advanced age, while the White House defended his stamina and downplayed concerns about his age affecting his re-election chances. White House press secretary Karine Jean-Pierre emphasized Biden's experience and accomplishments, stating that his age should not be the focus. Biden used humor during a pre-Thanksgiving pardoning ceremony, acknowledging his age and making light of the situation. Polls have shown that a majority of U.S. adults view Biden as too old to be effective for four more years, but the White House remains confident in his abilities.
