Yes, there are, but don't you think the entire process deserves some scrutiny? The reason the dems used shifty Schiff is because the intelligence committee can meet behind closed doors, meaning the press and the public have no way of knowing what's going on.
Plus, and this is really important, Schiff is controlling the entire process to the point that the republican members cannot call any witnesses. How can the process be impartial if the only person calling witnesses is a self-admitted Trump hater? The dude spent over two years telling us over and over, that he had the proof that Trump colluded with Russia. Where is it? Show your proof, Schiff.
And now, the pretense for using the intelligence committee instead of the judiciary committee, where any rational person would agree is where an impeachment inquiry should take place, is gone. The CIA link to the whistle-blower is no longer relevant, removing any reason for the inquiry to take place in intelligence. And now, since it was discovered that the whistle-blower had ties to Schiff, the testimony has been cancelled by... yes of course, Schiff.
None of this is in dispute, and should be of concern to anyone who cares about a fair process, and more importantly, not establishing precedent for the abuse of future presidents, regardless of party.
Anybody who thinks Schiff is conducting an impartial investigation is deluding themselves.
