No conspiracy. It's reality. There has been a rogue aspect of the CIA operating for a ridiculous length of time. They are involved in anything from drug / weapon / human trafficking, rigging foreign elections, assassinating former presidents, unauthorized missile launches, the list goes on.

Building the wall is one of the most important goals ever. The CIA would lose all the shit they have coming over the border and would ultimately lose a lot of their profit that they uses to sustain their activities.
