That's just a wild goose chase.
The process is much easier than that. The Trump defense team should simply demand to see the original whistleblower's complaint, along with the transcript of the testimony of Inspector General Michael Atkinson (who handled the complaint) before Schiff's secret House committee hearing.
The reason I believe that whistleblower IS Eric Ciramella, is he would have publicly came forward and denied it if he wasn’t. Think about it if they named you and you weren’t the WH.... I’d get a lawyer and have a statement out the next day.
