Former Secretary of State Hillary Clinton has revealed that President Joe Biden can count on her endorsement to stay in the White House for a second term if he chooses to run again in 2024.

“If he decides to run, he’s a sitting president,” Clinton told NBC News’ Yamiche Alcindor, who moderated a panel during the June 29 Aspen Ideas Festival that Clinton took part in.

“Would you endorse him?” Alcindor asked.

“I would endorse our sitting president, yes, of course,” Clinton replied, adding that Biden would be the person “most likely to win” in her view.

“Joe Biden beat in a huge landslide victory in the popular vote Donald Trump. I think that says a lot,” Clinton added.

Questions have swirled whether Biden, who is the oldest president in U.S. history and whose approval ratings have sunk sharply, will seek another term.

Biden has yet to officially declare his candidacy, though he and White House aides have said he plans to run.

Clinton, for her part, has flatly rejected a potential presidential run.

“No, no,” Clinton said when asked about the matter during a March interview on NBC’s “Morning Joe” program.

“But I am certainly going to be active in supporting women running for office and other candidates who I think should be reelected or elected, both women and men,” Clinton added, while vowing to “stay active” in debates around issues of key concern to Americans.

During her panel appearance at the Aspen event, Clinton issued a full-throated condemnation of the recent Supreme Court decision to overturn Roe v. Wade and let states decide for themselves whether abortion should be legal.
