Unsurprisingly, House Republicans' star witness is a fraud. The FBI kept Smirnov's testimony under wraps because it knew it contained biased and unsubstantiated claims the GOP would've celebrated as true. Even Republicans knew Smirnov was shady, but they were willing to look the other way in order to advance their fraudulent impeachment inquiry.
If Weiss really didn't investigate Smirnov's claims until recently, this is an impeachable dereliction of duty. Smirnov's claims were serious, and now it seems almost too convenient that his indictment might overshadow legitimate evidence against the Bidens. In addition, if the DOJ is in the mood for indicting informants it should go after those who fabricated evidence in the Trump-Russia collusion hoax.
