Obama DID do something.
Obama worked to get Hillary into the Presidency to hide the crimes of Hillary and the Obama administration.
Didn’t work out how Obama hoped, though........
And now we know about that which would have been hidden.
Spot on! The Collusion-gate became a means to distract President Trump from the hard task of draining the Swamp. Because of that, Collusion-gate has morphed into Obamagate. Our nation can no longer have persons in power shirk the laws to do what they want. If we let it go on, we will have hit killings, if that isn’t already happening. JFK comes to mind, here, for me.
