Trump's campaign issued a statement distancing the former president from a plan drawn up by former staffers
Project 2025 (and its auxiliary Trump’s “Agenda 47”) are a plan by right-wing extremists and other authoritarians to end America’s multiracial democracy and to replace it with a White Christian nationalist plutocracy.
A conspiracy is a plan by two or more people operating in private to advance their interests and goals above those of some other person(s) — or in this context the American people. Project 2025 is not a conspiracy. These plans are exhaustively detailed in a book titled “Mandate for Leadership: The Conservative Promise” and are regularly discussed at conferences, in interviews, and in other public forums. Project 2025 and its related plans, like Agenda 47, were not hatched overnight. As author and journalist Anne Nelson and other experts have been extensively documenting, Project 2025 and the other right-wing extremists’ and neofascists' plans to end America’s multiracial democracy have been years and decades in development
I think what they are trying to say is that the people behind Project 2025 aren't going to show their whole hand. This is just step 1. There are most likely plans and schemes that won't be revealed until they have implemented the first part.
