Of course, that beneift of the doubt breaks down at several points. After all, Donald Trump Jr., Mr. Manafort and Jared Kushner weren't shy about having their own meeting later in the summer with a Russian attorney who was advertised as acting as part of the Putin government's effort to help the Trump campaign and who supposedly had damaging information about Ms. Clinton. Nor did Mr. Sessions' wariness about contact with the Russians preclude him from meeting with then-Russian ambassador Sergey Kislyak at least twice and discussing matters related to the campaign and policy issues a President Trump might later address — meetings that Mr. Sessions initially failed to disclose and about which he later made statements that appear to be, at best, misleading. Nor did any concerns about the Putin regime's interference stop Michael Flynn, who would briefly serve as Mr. Trump's national security adviser, from talking to the Russian government after the election but before the inauguration (and then lying about it). Nor, of course, did it stop Mr. Trump from bragging to Mr. Kislyak in the Oval Office that he had fired FBI director James Comey because of the investigation into possible Russian collusion with his campaign.
