You mean the "Russian lawyer" that Obama let into the country without a visa under "extraordinary circumstances", met with Fusion GPS before and after her meeting at Trump tower; the same firm responsible for the PissGate dossier, which Obama used in the FISA court application as a reason to spy on Trump... if you can't figure out for yourself what's going on here, then I find your lack of critical thought disturbing.
From the 17 intelligence agencies? Oh wait, it was actually 4; interesting how they couldn't even get that right. I've been open to evidence for more than a year, and am still waiting for it. If you're asking whether I'd simply accept what someone from the intel agencies would say at face value; well unfortunately, they have a track record of being wrong, there's video of the Director of the NSA, James Clapper, lying under oath to Congress, so... they're going to need more than just words to corroborate that.
Well from the perspective of a top FBI official, that was a member of Mueller's investigation team, who already knew all the information regarding these alleged Russian contacts/meetings, the "17 intelligence agencies" saying Russia interfered in the election, everything the public would've known and more... before joining the investigation, Peter Strzok is found to be saying in private texts that all this you've just presented amounts to nothing substantial enough to warrant investigation; where the odds of Trump's team colluding with Russia are virtually nothing.
So it wouldn't be odd to think that, it's actually the rational view to take, for people that aren't in a war with reality; but I've found that those on the left in particular, have a lot of difficulty with this.
