As far as I can remember McKinsey was one of he leading companies involved in State Capture and briberty and corruption that nearly destroyed the country.
It is no wonder that McKinsey is involved in potential illegal activities - it is par for the course in companies with political links to the Democrats in the USA. The fact is the spider web of corruption in Washington is an absolute priority - but the FBI went AWOL in that regard and they themselves should be investigated for aiding and abetting bribery and corruption in the USA.
