There are many different ways the Obama administration could have reacted to the news that Page and Manafort had joined the Trump campaign. It could have given the campaign a defensive briefing. It could have continued interviewing Page, with whom the FBI had longstanding lines of communication. It could have interviewed Manafort. It could have conducted a formal interview with George Papadopoulos rather than approaching him with a spy who asked him loaded questions about Russia’s possession of Democratic-party emails.
Instead of doing some or all of those things, the Obama administration chose to look at the Trump campaign as a likely co-conspirator of Russia — either because Obama officials inflated the flimsy evidence, or because they thought it could be an effective political attack on the opposition party’s likely candidate.
From the “late spring” on, every report of Trump-Russia ties, no matter how unlikely and uncorroborated, was presumed to be proof of a traitorous arrangement. And every detail that could be spun into Trump-campaign awareness of Russian hacking, no matter how tenuous, was viewed in the worst possible light.
