Donald Trump may no longer be interested in Russia, but Russia is interested in him. Robert Mueller, the special counsel, has now indicted 19 people — including 13 Russians and five Americans who worked on Mr Trump’s campaign. That was just the start. When Mr Mueller gets round to Moscow’s election hacking, more Russians and Americans will surely be added. The Watergate investigation took two years to play out from burglary to presidential resignation. Nine months into the job, Mr Mueller looks to be on a similar timetable.

Familiarity lulls the mind. It is thus easy to miss the enormity of what is unfolding. Mr Mueller is playing a game of chess. Every move is made with his opponent’s king in mind. Last Friday, he boosted his defence by nailing Russia’s interference in the 2016 election. Do not take Mr Mueller’s word for it. HR McMaster, Mr Trump’s national security adviser, said Russia’s role was “now incontrovertible”. That makes it far harder for the president to fire Mr Mueller — something he has tried to do more than once. I would bet Mr Trump now sees General McMaster as a sacrificial pawn.

Mr Mueller is skilled at messing with his opponent’s head. Both Mr Trump and Mike Pence, the vice-president, say the charge sheet showed Russia had no effect on the outcome of the US election. In fact, the 37-page document was silent on Russia’s impact. It is telling that America’s two most senior statesmen are reading things that are not there.
