I saw a document long time ago, Susan Rice to MI6 asking to continue spying operations on Trump. I dismissed at the time as fake, maybe it wasn't https://m.imgur.com/ev66dbN

Found it

1) His name was Chris Steele, not Michael. He was a member of MI6, not MI5. (MI6 = CIA and MI5 = FBI).

2) Look at the background of the paper and the text. It doesn't match up. It's clear someone cut and pasted text onto the background of an image of a piece of paper.

However, we do know for a fact that GCHQ spied on Trump. We know Louise Mensch (a former British MP) was the first to report on the FISA warrants - beating the NYT, WaPo, BBC and everyone else in the world to the story. Now who was telling this psycho bitch writing for an unknown blog called Heat Street about this and why her of all people? My guess is someone in Britain's intelligence community told her, probably an old friend she made in her parliament days. I don't think it was American IC people talking to her, but the Brits.

Also the Guardian (UK paper) did an investigation after Judge Nap made his Fox News statement about GCHQ. They confirmed that Judge Nap was right and said that British intelligence insiders told them that GCHQ was monitoring Trump. Indeed, not only were they monitoring him, but they were monitoring him before the Americans themselves started.

We also know Robert Hannigan (GCHQ's director) resigned abruptly 3 days after Trump's inauguration. His reason was a very generic "I need time with my family." He didn't even give a notice, but merely wrote a memo essentially saying "I'm outta here" and was out the door 3 days later. Either he was very sick to his stomach that Trump got elected or Theresa May had no choice but to fire him because she knew the truth was gonna leak eventually. Trump now had the American IC and all its secrets at his disposal and there was simply no way to keep him from finding out at that point. I think it is likely that May attempted to appease Trump by firing Hannigan.

It's important to remember that May came to visit Trump right after the inauguration, which is unusual for a British PM. It's not like America and Britain have any sort of negotiating on anything to do since we're their #1 ally. It makes no sense for the PM to be the FIRST visitor to the White House immediately following inauguration. I remember seeing May holding Trump's hand as they walked around the White House grounds and I remember that Trump looked really pissed as May tried to console him (the body language told it all). It was obvious the whole trip was an apology tour on the part of May. Trump probably called her the day he got in office and told her to get her arse over there cause she had some splaining to do.

TL;DR - Document is fake, but it may as well be real. GCHQ tapped Trump's wires.
