Sure. Testimony all day today in the Senate. Everyone conceded that "the Russians hacked the DNC server and Podesta". It was in the Mueller report. Except, as far as I know, that is based entirely on Crowdstrike. But everyone accepts that as fact.
Maybe... for TV. It is quoted nowhere as supportive legal evidence that I am aware of. Mueller himself drowned the thing when he appeared before the House to testify... said he never heard of Fusion GPS - while investigating Russian interference in the 2016 elections. A total embarrassment.
Roger Stone was going to use the FBI / Crowdstrike anomaly to get the case against him dismissed; it was presumed the FBI could not sustain the claim that the Russians fed DNC messages to WikiLeaks; I don't know why that didn't work for Stone. I don't see how the FBI could introduce evidence in court about something they never verified --- oh, yeah: FISA and the Steele Dossier. We'll just see about that.
