I will start by saying this could be very triggering for most, so tread warily. SA.
Secondly this account has been reported, investigated, and researched by many independent journalists, who strongly feel it is legitimate, but absolutely nothing on mainstream media.
The person is Sascha Riley (William Sascha Riley) a veteran. He has been speaking out for some time, mentioning names of high profile characters in the US government including trump and their cesspool behaviour. (An understatement). I have been horrified by his account or the parts I could bear to listen to. His story is gaining traction and more recently he has had to leave America , I believe, due to threats to his safety.
Trump appears to have such a strangle hold on foreign and domestic news organisations that they're scared to report on this even though it has been 'out there' for some time.
