Alan ArchibaldFrom the get-go, I've held the same view as Dean: "Trump’s admission that he fired FBI Director James Comey to relieve the pressure of his investigation into Russia was “basically confessing to obstruction of justice.”"
Put yourself in Trump's shoes and imagine you've been pulled over by a cop "doing 80" in a 55 zone.
Now imagine rolling down your window and saying to the cop, "You're fired!"
Nixon did not choose to step down because he was charged with authorizing the Watergate break-in and subsequent theft.
Nixon stepped down because he was charged with "obstruction of justice," a crime of which he was demonstrably guilty.
In the end, Tricky Dick held on to power as long as he could. But for many months he knew that "obstruction" would eventuallly roast his goose.
If America still has a bone in its body that believes in "The Rule of Law," it will be Devious Donald's "obstruction of justice" charge that roasts his goose too whether or not there was any malfeasant activity with the Russians.
