White House as crime scene: how Robert Mueller is closing in on Trump

The legal net around Donald Trump’s beleaguered presidency tightened dramatically this week with news that a grand jury has been established a few hundred yards from the White House, to pursue evidence of collusion with the Kremlin. The grand jury is also clear evidence that the inquiry is widening, not tapering off. Robert Mueller’s investigators are reported by the New York Times to have asked the White House for documents related to the administration’s first, short-lived national security adviser, Michael Flynn, who resigned after being found to have concealed the full nature of his contacts with the Russian ambassador to Washington, and who is also under scrutiny for his lobbying work for Turkey during the campaign.
