Former US vice president Kamala Harris revealed that former president Joe Biden’s aides didn’t like a March 2024 speech she gave in which she called for a temporary ceasefire in Gaza, claiming that Biden’s inner circle felt she was outshining him, according to excerpts published Wednesday from her forthcoming book.

She made the speech in question at a commemoration of Bloody Sunday, the 1965 incident in Selma, Alabama when civil rights marchers were attacked by police.

“I gave a strong speech on the humanitarian crisis in Gaza. Desperate people had been shot when they swarmed a food truck, and I spoke of families reduced to eating leaves or animal feed, women prematurely giving birth with little or no medical care, and children dying from malnutrition and dehydration,” Harris recalled in an excerpt, published in The Atlantic, from her upcoming book, “107 Days.”

“I reiterated my strong support for Israel’s security and called on Hamas to release the hostages and accept the ceasefire agreement then on the table. I also called on Israel for greater access to aid,” she continued.

“It was a speech that had been vetted and approved by the White House and the National Security Council. It went viral, and the West Wing was displeased. I was castigated for, apparently, delivering it too well,” Harris claimed.

The speech did indeed make headlines as it appeared to be the first time that the US had called for a ceasefire in Gaza. The line was immediately cheered by those in attendance — so much so that the applause drowned out Harris’s clarifying that she was referring only to a six-week truce that had been under discussion, not something more long-term.

She was still seen by some as taking a slightly tougher approach to Israel than Biden — something both of their offices denied at the time.

The speech was used to highlight a broader frustration Harris had, not with Biden, but with the aides around him.

“Their thinking was zero-sum: If she’s shining, he’s dimmed. None of them grasped that if I did well, he did well. That given the concerns about his age, my visible success as his vice president was vital. It would serve as a testament to his judgment in choosing me and reassurance that if something happened, the country was in good hands,” she wrote. “My success was important for him. His team didn’t get it.”

Harris also noted in the excerpt that Biden, who was already struggling in the polls due to the perception that he was too old to serve, “started taking on water [in 2024] for his perceived blank check to [Prime Minister] Benjamin Netanyahu in Gaza.”

The former vice president said it smacked of “recklessness” to let Biden run for a second term as president, and admitted that the then-81-year-old got “tired” and was prone to stumbles that showed his age.

The 60-year-old Harris also accused Biden’s team in the White House of failing to support her while she was his deputy, and at times of actively hindering her.

Biden stunned the world by dropping out of the race in July 2024, weeks after a disastrous debate with Trump sparked questions about his age and mental acuity.

Harris denied that there had been any conspiracy to hide Biden’s condition but said it was clear there were issues with his age.

“On his worst day, he was more deeply knowledgeable, more capable of exercising judgment, and far more compassionate than Donald Trump on his best,” she wrote. “But at 81, Joe got tired. That’s when his age showed in physical and verbal stumbles.”

Harris further lashed out at White House staff who, she said, failed to support her when she was vice president, writing that Biden’s team did not want her to upstage her boss.

“When the stories were unfair or inaccurate, the president’s inner circle seemed fine with it. Indeed, it seemed as if they decided I should be knocked down a little bit more,” Harris wrote.

She added that she had “shouldered the blame” for Biden’s border policy, which Trump capitalized on in the election.

Harris also appeared hurt that Biden barely referred to her in his televised Oval Office address about his decision to drop out of the race, after which he anointed her as his successor as Democratic nominee.

“It was almost nine minutes into the 11-minute address before he mentioned me,” she said.

Harris went on to lose to Republican Trump after running the shortest presidential campaign in modern US history, lasting just over three months — the “107 days” in the title of her memoir.
