They can’t go after Obama because they helped him violate the Constitution.
Almost everyone in the District of Corruption except for President Trump was complicit.
Obama could not have usurped the office without their assistance.
That has obligated them to not only cover up his myriad crimes, but to occasionally assist in them, too, as well as undermine a President of their own party.
Clinton went after the generals that defied him. I say go after the muslim that married her brother. The price of freedom is eternal vigilance so POTUS is tasing care of business in regards to China and the wall. Leave him be.
