That is completely new to me.
Wow. Thanks for posting it.
One of the best kept secrets in America is how anything set up by one president by ExO, can be killed/eliminated with a new ExO deleting the former ExO.
For example JFK used an ExO to allow government employees to unionize. Trump can eliminate that with an a different ExO.
Every Exo enacted by JFK, LBJ, Nixon, Ford, Carter, Reagan, Bush1, Clinton, BushII or Obozo, can be cancelled by Trump.
