Since you only read troll news, I'll copy paste here:
Spot fires of other false rumors and questionable reporting popped up as well — for example, the conspiracy theory site TheDuran.com claimed that Schiff had “colluded” with a Ukrainian oligarch, offering no other evidence than a 2013 fundraiser for Schiff held by businessman Igor Pasternak, who has strong ties to Ukraine and who runs a small airships manufacturing company in Montebello, California.
On 6 February 2018 the British tabloid Daily Mail, along with right wing web sites including Breitbart and The Daily Caller regurgitated the original reporting of journalist Julia Ioffe in The Atlantic, part of which revealed Schiff had taken a phone call in April 2017 from two Russian “pranksters” impersonating a Ukrainian politician who led him to believe they had information about the Russia investigation. Ioffe’s report includes a key detail the aggregators neglected — the “pranksters,” Vladimir Kuznetsov and Alexey Stolyarov, may have Kremlin ties. [Audio of the call recording seems to indicate Schiff "played along" and said he'd be interested in naked photos of Trump, but he immediately reported the call to the FBI.]
You can monitor the live status of Russian troll campaigns here--looks like they've shifted from Schiff to Pelosi now, so expect a bunch of fake news on Pelosi today:
