What are Project 2025's ties to the Trump campaign?

(NewsNation) — Questions surrounding former President Donald Trump's connections to the controversial conservative plan Project 2025 are intensifying as he's set to accept the presidential nomination at the Republican National Convention this week.

Trump has previously disavowed the plan, posting on his social media site that he has “no idea” who is behind Project 2025 and knows "nothing" about it, but dozens of people who worked closely with him and helped shape his administration are involved in the plan.
