!! BREAKING from @NatashaBertrand: Trump has fired the intelligence community inspector general, Michael Atkinson, who first informed Congress of the existence of the Ukraine whistleblower report. https://www.politico.com/news/2020/04/03/trump-fires-intelligence-community-inspector-general-164287

I believe this leaves no Senate-confirmed officials at the top of ODNI.

Per a congressional source:

"Atkinson was only informed tonight that Trump had fired him, and he has been placed on administrative leave effective immediately."

Administrative leave helps skirt a requirement that the intel committees get a 30-day heads up before removal.
