It is not a lie that Trump heavily and suspiciously favors pro-Russian policy. It is not a lie that he and his campaign had over 250 contacts with Russia. It is not a lie that Russia contrived a strategy to help Trump win. It is not a lie that Trump has blocked and/or slow-walked Russian sanctions authorized by Congress. It is not a lie that Trump keeps touting what Putin says (we did not interfere, no interest in Venezuela, etc.). It is not a lie that Trump refuses to acknowledge Russian interference in the election. It is not a lie his campaign changed the GOP platform to a pro-Russian stance on Ukraine. It is not a lie that his campaign gave the Russians polling data. It is not a lie that that the Trump campaign recevied advance word of leaks of stolen emails by the Russians.
And then we get to obstruction.
It is not a lie that Trump fired Comey because Comey would not block the investigation into Flynn and pledge loyalty to Trump. It is not a lie that Trump repeatedly fabricated reasons to fire Mueller. It is not a lie that Trump told his counsel get Mueller fired -- and then asked counsel to lie and say he had not done so. It is not a lie that Trump told the Russians that he had taken steps to thwart the investigation.
Pesky facts, sir. Taken singularly they are bad enough. Taken together they show a corrupt President who should be imprisoned. And it will forever be a stain on the reputation of the GOP that they did not have the stones to do what is right here.
