Dirty tricks still abound. If you trust the dirty-tricksters, you're part of the problem.
Not Glenn Greenwald's best writing, rather redundant; but, he does point out the most important aspects.
“The professor’s interactions with Trump advisers began a few weeks before the opening of the investigation, when Page met the professor at the British symposium,” the Post reported. While it’s not rare for the FBI to gather information before formally opening an investigation, Halper’s earlier snooping does call into question the accuracy of the NYT’s claim that it was the drunken Papadopoulos ramblings that first prompted the FBI’s interest in these possible connections. And it suggests that CIA operatives, apparently working with at least some factions within the FBI, were trying to gather information about the Trump campaign earlier than had been previously reported.
Whatever else is true, the CIA operative and FBI informant used to gather information on the Trump campaign in the 2016 campaign has, for weeks, been falsely depicted as a sensitive intelligence asset rather than what he actually is: a long-time CIA operative with extensive links to the Bush family who was responsible for a dirty and likely illegal spying operation in the 1980 presidential election. For that reason, it’s easy to understand why many people in Washington were so desperate to conceal his identity, but that desperation had nothing to do with the lofty and noble concerns for national security they claimed were motivating them.
This is interesting too:
... CIA operative, Stefan Halper.
Four decades ago, Halper was responsible for a long-forgotten spying scandal involving the 1980 election, in which the Reagan campaign – using CIA officials managed by Halper, reportedly under the direction of former CIA Director and then-Vice-Presidential candidate George H.W. Bush – got caught running a spying operation from inside the Carter administration. The plot involved CIA operatives passing classified information about Carter’s foreign policy to Reagan campaign officials in order to ensure the Reagan campaign knew of any foreign policy decisions that Carter was considering.
Russiagate began in someone's dirty-trickster mind. It was conjured up for US Neocon-imperialist Russiaphobia reasons, nothing more.
