I have heard that 2025 is the blue print for when Trump returns but it got leaked prematurely and things were falsely added to it. It is supposed to be 750 pages but 1000 pages got released so Trump had to denounce it.
That dinner by the Heritage Foundation where Trump spoke in favor of Project 2025 was before the 900 page document. What he heard, at that point, was not even in print and, was a rosy account so he would buy into it. Perhaps, as I suspect, such a positive account that they would get Trump’s funding. Little did Trump know that when the full Project 2025 was printed, it had lots of bad policy. It was then, he moved away from it.
