McKinsey & Company is a known CIA front company.
They even worked with Brennan in 2015 to revamp the CIA management.
The top management of Burisma was former McKinsey.
Brennan deserves to be in prison. While head of the CIA he still had a agency to administer, and hired M&C to make changes the CIA managment in 2015. Buttigieg worked at McKinsey & Company from 2007 to 2010, then went on to campaign for state offices in Indiana. He left M&C five years before they got the CIA contract.
Anyone trying to claim Buttigieg was involved with the CIA while at McKinsey & Company is simply refusing to do basic research. Even if he did work on matters for the CIA between 2007 and 2010, no one has offered any suggestion of what he did, let alone if it was dubious in anyway.
I am not defending Buttigieg's politics here. I am questioning what looks like an instinctive reaction to create a conspiracy theory, when there is no conspiracy in the first place.
