We’ve known for quite some time that President Donald Trump’s political opponents paid for the opposition research that led to the infamous Russia dossier of assorted allegations — some subsequently confirmed, some not, some salacious, some not — involving the Republican’s connections with the Putin regime. We’ve known for months that a wealthy Republican opposed to Mr. Trump’s candidacy initially paid for it, and after the primaries, Democrats took over. It turns out those Democrats were the Hillary Clinton campaign and the Democratic National Committee via a Washington law firm that hired the opposition research company that hired the former British intelligence agent who did the digging. That’s interesting, but mainly in that none of the contents of the dossier became public until after the campaign was over. Apparently the Clinton camp showed some modicum of compunction about throwing around unsubstantiated allegations. How quaint.
