Two additional points. First, the Post describes the CIA’s report as “secret.” So how is it that everyone knows about it? The answer, obviously, is that officials who were privy to the secrets improperly provided them to the press. (Here we should note that we do not fault the Post or the Times for having published the information they received, and that we would have done the same.)
Second, according to the Times report, even if the Russians were trying to help Trump, they didn’t expect to be successful:
The Russians were as surprised as everyone else at Mr. Trump’s victory, intelligence officials said. Had Mrs. Clinton won, they believe, emails stolen from the Democratic committee and from senior members of her campaign could have been used to undercut her legitimacy.
So American officials made secret information public with the effect—and, one may surmise, the intent—of raising questions about the legitimacy of President-elect Trump. That’s exactly what they accuse the Russians of having planned to do to Mrs. Clinton.
