Trump fired Comey, and he was planning to do so for about at least a week. I believe that while Comey was a bit clumsy at handling facts last week, there really wasn't enough ground for him to get fired - especially since his clumsiness actually pushed forward a stronger case against Abedin and co. I'm guessing that Trump wants to stymie all possible efforts by the government into the Russia investigation. And while the other agencies charged with that task are severely understaffed, the FBI was the frontrunner in leading the investigation - till now. From asking one of my cousins who works for Sen. McCain, it seems that camp is very very suspicious about this.
Despite his Republican pedigree, Comey was selected by President Barack Obama to replace Mueller atop the FBI in 2013, in part because of his reputation for independence and integrity. The Senate easily confirmed him.
I'm actually surprised the public has silently accepted the words of a president long known for misleading them.
Welcome to 1984, America, a world where the words are fed into your mouth by the government! Or idk, wilkommen America zu Reich Deutscheland im jahr 1933?
