[Unable to defend Trump], Republicans are now saying this: Nothing is more important than revealing the identity of the whistleblower whose complaint touched off this scandal. Without knowing who that person is, we can’t judge Trump…

While it might be of some historical interest, at this point the whistleblower’s identity is irrelevant. No one is asking that we take their word on anything. They sounded the alarm that touched off an investigation, but the evidence that will provide the grounds for impeachment is coming from Trump’s own words and the testimony of multiple officials in his administration, not the whistleblower.

The whistleblower was the equivalent of someone who made an anonymous call to the police saying that there’s a robbery going on at the First National Bank. Once the police get there and catch a bunch of guys wearing masks and holding sacks of money, it doesn’t matter who made the call or what their motives were. Maybe it was a passerby, or maybe it was the estranged wife of the leader of the gang. It doesn’t change the fact that the bank was robbed and we know who the robbers are.

Furthermore, just about everything the whistleblower alleged has been corroborated…

All this has been confirmed by Trump’s words and the testimony of administration officials and career civil servants. We don’t need to know the whistleblower’s identity to assess their credibility, because we aren’t relying on their credibility.
