Former Vice President Kamala Harris concedes she made a grave mistake by holding back from advising her former boss, Joe Biden, against pursuing reelection in 2024, declaring that: “In retrospect, I think it was recklessness.”

In an excerpt from her upcoming book “107 Days” published Wednesday in The Atlantic, Harris says that “of all the people in the White House, I was in the worst position to make the case that he should drop out.”

“I knew it would come off to him as incredibly self-serving if I advised him not to run,” she writes.

But Harris acknowledged that she was wrong to rest such an important call on just Biden and his wife, Jill.

“‘It’s Joe and Jill’s decision.’ We all said that, like a mantra, as if we’d all been hypnotized,” she writes. “Was it grace, or was it recklessness? In retrospect, I think it was recklessness. The stakes were simply too high. This wasn’t a choice that should have been left to an individual’s ego, an individual’s ambition. It should have been more than a personal decision.”

Harris’ willingness to create some distance between herself and the former president stands in contrast to the approach she took toward Biden after she became the Democratic nominee following his withdrawal from the election in July 2024.

In an interview with “The View” in October 2024, she said she wouldn’t have done anything differently than Biden over the past four years — a statement that Republicans used to attack her.

Still, Harris made clear in the excerpt that she did not believe Biden was unfit to serve despite his poor performance in the debate against now-President Donald Trump in June 2024, which prompted calls for him to exit the race.

“On his worst day, he was more deeply knowledgeable, more capable of exercising judgment, and far more compassionate than Donald Trump on his best. But at 81, Joe got tired,” she writes.

“I don’t believe it was incapacity. If I believed that, I would have said so. As loyal as I am to President Biden, I am more loyal to my country,” she continues.

The former vice president also did not hold back on calling out Biden’s team, alleging that they undermined her and did not defend her from unfair attacks, without realizing that their response ended up hurting their boss.

“If she’s shining, he’s dimmed. None of them grasped that if I did well, he did well,” she writes. “That given the concerns about his age, my visible success as his vice president was vital.”

Over the summer, Harris announced she would not pursue a run for California governor to succeed Gavin Newsom who is term-limited but has yet to rule out a 2028 presidential bid.
