Trump's advisors helped a Russian campaign to elect Trump. His campaign manager was
literally giving confidential polling data to oligarchs linked to the Kremlin. That's not collusion in your book?
Trump's former campaign chair tells Insider he shared polling data with longtime business associate Konstantin Kilimnik to help secure business deals.

They weren't "based upon the Dossier" and the warrants were, pardon the pun, absolutely warranted. The investigation was already underway and bits of the dossier about Trump foreign policy adviser Carter Page (not Trump) were used in the warrant application. Page had attended high-level meetings with Russians during a trip to Europe, and Page was lying about it at the time. The Dossier noted that he had met with Russians (and was correct on that point). That's what was used in the warrant.
I certainly think it's worth of investigation that a a major-party Presidential candidate's foreign policy advisor, who years prior been suspected of being a Russian intelligence asset, was lying about meeting with a deputy Russian Prime Minister while working for said major-party Presidential candidate.
Finally, the FISA warrants of Page continued even after Trump was inaugurated. You know for a FISA warrant of an American citizen you have to show the judges you are collecting valuable information or otherwise they get shut down? Investigators went back to the court
at least four times and demonstrated that they were collecting valuable information from the wiretap of Page. So it wasn't some sort of Obama fishing expedition.
