I had strong suspicions back in late 2015 and early 2016 what was happening. The two school-terror hoaxes, targeting the most blue and urbanized districts on either coast, were not perpetrated by ISIS or some foreign terrorist. The hoaxes were timed to precede major presidential debates or town halls by about a day's time. To the galactically naïve, this is known as the old "Reichstag Fire" trick, in one of its many forms.
The FBI traced the hoaxes to IP addresses in what had once been East Germany. Interesting coincidence -- with Vlad Putin's early career posts. But figure the Russians would have assets in Germany still. They got Anna Chapman into the US, didn't they?
I would not be skeptical about the grounds for impeachment, but I would worry strongly about derailing an objective investigation. At minimum, knowing of an attempt to put the thumb on the scale of our elections, and failing to tell the authorities about it, is "Misprision of a felony," which is also a felony. If Trump did more than that, it would only make impeachment a done deal. I had been using the word "Treason" for the last three or four months, because I saw all this coming. Only the other day, Congressman Moulton used the same word in the same context of the same news and issues.
It depends on congress, and it depends on honest, dedicated civil servants. But both have been sliding downhill for years -- and not because of the Obama administration.
As for Congressman Lewis and Conyers -- they're right. And I probably say this to spit in the face of Trump supporters. Trump is as legitimate as a toddler in a whorehouse. If we could use Trump's favorite technique and waterboard Vlad Putin, we might find out for sure where Donnie-Boy has been. Of course, you can speculate about his wife on the front page of the New York Post.
She has "stars," you see . . . . .
