I think this is an interesting point. Something that came out of that imbroglio was that Trump - per Trump - had never even
met the man on the NSC in charge of coordinating Ukraine policy and reporting to the President. He was ultimately fired.
The NSC Homeland Security Advisor in charge of pandemic threats was fired in 2018. He was never replaced. His staff was also canned. Bossert btw was the guy who was the whistleblower on the Trump-Lavrov meeting. I'm sure his dismissal and the removal of the position was completely unconnected. He also had responsibility, besides cybersecurity and other asymmetrical threats, of counseling the President directly on pandemic threats.
He's had some interesting things to say during this, but even if he was there I really kind of doubt the President woudl be meeting with him anyway.
We're on our 6th Sec. DHS. Our 4th NSA. The WH does not have a Chief of Staff.
