Project 2025 was created by The Heritage Foundation, a right-wing conservative organization.
Several of the authors of Project 2025 were Cabinet secretaries and other officials during Donald Trump's administration.
"Six of his former Cabinet secretaries helped write or collaborated on the 900-page playbook for a second Trump term published by the Heritage Foundation. Four individuals Trump nominated as ambassadors were also involved, along with several enforcers of his controversial immigration crackdown. And about 20 pages are credited to his first deputy chief of staff." - CNN
