Obama used a phony DNC dossier to obtain a FISA warrant to spy on the Trump campaign and transition teams by the intelligence community. The firing of Comey was not obstruction of justice and McCabe testified before Congress that the firing had no effect on the ongoing investigation.
The unmasking of Flynn was a real crime. And so was a corrupt, politicized FBI that had protected Hillary from prosecution. Comey was guilty of obstruction of justice by making a decision not to prosecute, which was not his to make. The DOJ and the AG make that decision.
That seems clear insofar as it goes. So Why is CNN beating the drum for obstruction, obstruction and more obstruction by trump today?
