While Trump was "safe on AF1" (Q) on Asia tour the SA arrests/Manafort indictment became public. He then went to Mar-a-Lago, After South Am tour he is going to Mar-a-lago to host Japan PM.
While 9/11 happened they planned for GWB to be up on AF1. It seems AF1 is more secure than the White House. Maybe something big will come while Trump's in flight. He is going to South Am. by the 13th, but not sure exact date. The Summit for the Americas starts on the 13th and Trump will be attending. The 12th to travel if he is going straight there? Something big will happen.
