Robert Mueller's report (https://www.justice.gov/archives/sco/file/1373816/download) found no such evidence though.

p.181 "The investigation did not establish that the contacts described in Volume I, Section IV, supra, amounted to an agreement to commit any substantive violation of federal criminal law—including foreign-influence and campaign-finance laws, both of which are discussed further below. The Office therefore did not charge any individual associated with the Trump Campaign with conspiracy to commit a federal offense arising from Russia contacts, either under a specific statute or under Section 371’s offenses clause."

"The investigation did not establish any agreement among Campaign officials—or between such officials and Russia-linked individuals—to interfere with or obstruct a lawful function of a government agency during the campaign or transition period. And, as discussed in Volume I, Section V.A, supra, the investigation did not identify evidence that any Campaign official or associate knowingly and intentionally participated in the conspiracy to defraud that the Office charged, namely, the active-measures conspiracy described in Volume I, Section II, supra. Accordingly, the Office did not charge any Campaign associate or other U.S. person with conspiracy to defraud the United States based on the Russia-related contacts described in Section IV above."

p. 183 "The investigation did not, however, yield evidence sufficient to sustain any charge that any individual affiliated with the Trump Campaign acted as an agent of a foreign principal within the meaning of FARA or, in terms of Section 951, subject to the direction or control of the government of Russia, or any official thereof. In particular, the Office did not find evidence likely to prove beyond a reasonable doubt that Campaign officials such as Paul Manafort, George Papadopoulos, and Carter Page acted as agents of the Russian government—or at its direction,control, or request—during the relevant time period."

Shouldn't Mueller have at least included all the evidence that the FBI had taken to this court in the report?

Much of that evidence had been disproven (and not in the "You can't prove a negative" sense, but in the "People and actions were quoted that refuted the accusations and were impossible according to other evidence"), rendering the rest of that dossier's accusations suspect/discredited. Plenty of true things were in the dossier, but none of them were incriminating, except in as much as Trump has open hands and poor taste in business partners.

They already knew the dossier was flimsy and had problematic provenance, didn't they? There seems like no way that could possibly have been the only evidence used to justify the warrants, or to keep a special council investigation running for 2 years, or have Adam Schiff as ranking member on the House Intelligence Committee clearly state that he had seen ample evidence that Trump colluded with Putin to hack the election. Surely there must be much stronger evidence out there. The simplest explanation says that Putin and Trump got to Mueller and Schiff and others to keep them quiet and prevent the evidence getting out. What's the alternative?

The alternative is that Obama and Biden, or anyone in their bureaucracy, got to the FBI and convinced them to accept their crazy dossier.

This is entirely he said she said, without the records of the court in question - and even then would likely be he said she said.

A very far fetched conspiracy theory that would really have astounding implications for the entire system of government inthe country. What's more likely happened is Putin and/or Trump got to Mueller and Schiff and others to silence them and bury all the evidence.

In the most polite way possible, what are you talking about? How does anything you've quoted have anything but a tenuous, situational connection to the FISC court?

The Mueller report said they found no such evidence, and therefore it failed to consider the evidence put before the FISC court in the first place.

Do you deny that Trump colluded with Putin to hack the election? Or that there was strong evidence of him having done so?
