You can read Project 25 here. As summarized by the Kamala Harris campaign, it does the following: (1) Donald Trump and his MAGA allies plan to reward political violence, prosecute political opponents, and pardon January 6 insurrectionists; (2) Trump and his allies are planning a massive expansion of presidential power, with plans to restructure the government and concentrate power in Trump’s hands. (3) Donald Trump brags about abortion bans across the country – what’s next is even worse; and (4) Trump is promising to cut Social Security and terminate the Affordable Care Act to fund tax giveaways to his billionaire buddies and lower taxes on big corporations in a second term.
Trump is now trying to distance himself from the plan to centralize power in the executive branch. I don't believe him because he routinely lies.
