Collusion isn't a crime anyway. Conspiracy is but that's neither here nor there. He hasn't done anything remotely prosecuteable and every time that fool Al Green attempts to impeach, it strengthens President Trump's position.
Apparently Trump’s National Security Advisor sends out a message to his buddy that the Russian sanctions will be dropped and the deal is ready to go ahead….. during the transition itself…. Huh ….. So Trump is not getting anything under the table? How is this not corruption? Plus he is so lame that he actually blames the Obama administration for passing Flynn’s security clearance.
