"Cunningham also deployed for numerous public health emergency responses, including Superstorm Sandy, Ebola, and Zika."
From a WaPo article I didn't click on, but here's the link.

Cunningham was a Harvard educated epidemiologist who was a leader in his field. No WAY was he suicidal from "not getting a promotion". BULLSHIT.
He saw something fucked up, my guess is with the phony ebola outbreaks. (Ebola is real, but lab created and released when WHO/CDC/UN etc… wants access to poor Africans and/or money from taxpayers.
