Former US Vice President Kamala Harris announced Thursday that she will release a memoir reflecting on her brief but historic run for president. This comes a day after Harris announced that she will not be running for California governor in 2026.The book, titled ‘107 Days,’ will be published on September 23 by Simon & Schuster.“Just over a year ago, I launched my campaign for President of the United States,” Harris said in a video posted on X.“107 days traveling the country, fighting for our future — the shortest presidential campaign in modern history. Since leaving office, I’ve spent a lot of time reflecting on those days and with candor and reflection, I’ve written a behind-the-scenes account of that journey. I believe there’s value in sharing what I saw, what I learned, and what it will take to move forward,” she added.Harris ended up leading the Democratic ticket after former President Joe Biden dropped out last July following a widely criticised debate performance. She was defeated in the November election by Donald Trump. Had she won, Harris would have been the first woman and the first woman of color to become president of the US.Simon & Schuster CEO Jonathan Karp declined to give details about what Harris will discuss in the book, including her views on Biden’s fitness for office, but said Harris “addresses everything we would want her to address.”Simon & Schuster described the book as a “page-turning account,” offering “surprising and revealing insights.”“Kamala Harris is a singular American leader,” Karp said in a statement. “‘107 DAYS’ captures the drama of running for president better than just about anything I’ve read. It’s one of the best works of political nonfiction Simon & Schuster has ever published. It’s an eyewitness contribution to history and an extraordinary story.”Harris previously released ‘The Truths We Hold: An American Journey’ in 2019 through Penguin Books.
