The paper tearing was simply the latest splash of symbolism. The impeachment trial in the house, the endless floor speeches throwing in everything but the kitchen sink (though there was fried chicken somewhere as I recall), the demands of new witnesses, the charade of Constitutional duty, all of it. All of it was symbolism. The Dems knew The President wasn't going to be taken out. It was all kabuki theater, a show trial, symbolism. All so they could show their base that "they tried, but the criminal Republicans cheated them". It's all just to keep stoking the flames of hatred and resentment and anger until the election so when Trump gets re-elected, the hordes of the Left will go on the attack. And her final act of the Impeachment Fail was acting like a two year old and ripping up the speech. Yet the left is applauding her for it.
We have all the proof we need.
