And this one from the Guardian feed is the Coup de grase:

If confirmed, the news that a grand jury has been convened and has started issuing subpoenas suggests that the investigation into the Trump camp’s links with Moscow has entered a new phase.

Under US law, grand juries (which are larger than normal 12-person court juries) have sweeping powers to compel witnesses to appear, to call for the presentation of documents and to issue indictments.

While the Republican majorities in the House and Senate could hold back congressional investigations and a new FBI director to kill off its counter-intelligence investigation, a grand jury is not under Trump’s control. He may not be able to stop the Russian collusion affair from going to court.
