• Trump rails against Russia coverage.

After watching a golf tournament at one of his clubs, President Trump turned to Twitter to excoriate Hillary Clinton and to rebuke the news media for its coverage of his son’s meeting with a Russian lawyer in June 2016.

We profiled two others at that meeting: Rinat Akhmetshin, who has shown himself to be skilled in the muscular Russian version of what in American politics is known as opposition research, and Aras Agalarov, a property developer known as a fixer for the Kremlin’s toughest jobs.

Our reporters also investigated a $17 million payment to Paul Manafort, Mr. Trump’s former campaign chairman, from a Kremlin-linked political party in Ukraine.
