Not a joke. I knew a guy who was well connected to Biden and the Democratic party. He was a businessman/developer who was also visiting Ukraine frequently around 2015/2016. He knew a lot about developing natural gas pipelines Died of complications from a blood clot mid-June, 2017. Won’t find much about him on the internet anymore, except for his obituary.
Bingo. Spotlight on him. Tougher to kill him.
