But what do the facts show? There is a growing, mostly undisputed body of evidence describing contacts between Trump associates and Russia-linked operatives. Trump partisans have claimed that Mueller’s investigation is biased because some members of his staff supported Trump’s rival, Hillary Clinton. But Deputy Attorney General Rod J. Rosenstein disagreed Wednesday, arguing that Mueller “is running his office appropriately.”

As Republicans seek to discredit the investigation, it’s useful to remember just what we’ve learned so far about how the Trump campaign sought harmful information about Clinton from sources that, according to U.S. intelligence, were linked to Moscow. This isn’t a fuzzy narrative where the truth is obscured; in the Trump team’s obsessive pursuit of damaging Clinton emails and other negative information, the facts are hiding in plain sight.
