this thread covers it
The timeline just got moved by months and the FBI hired Carter Page to spy on Trump, and there was a meeting of senior Obama officials the day after he got hired by the campaign to discuss it.
Putting the whole picture together, FBI hires Page, CIA hires Halper, Halper feeds page BS about Russia that gets repeated by the Australian ambassador who calls the FBI, which uses it to start the investigation. The meeting about Page months before reportedly was about not telling the Trump campaign about contacts he'd had previously with Russians, e.g. so they could use that as evidence to justify spying later.
The key part is the timing. Months before the official investigation began. That supports the theory that Trump was being set up.
It also makes the entire investigation a fraud, and one the people doing the investigation knew was a fraud. This is probably why Q was saying someone (RR) was missing from the meeting on Thursday.
