Obama has run guns to Mexico and assisted in the murder of thousands in the Mexican drug war.

Obama has used the IRS to harrass political opponents. This was one of the charges that brought Nixon down. And they didn't have real proof on Nixon. Tons of proof on Obama.

The NSA spy network. Unconstitutional but embraced and expanded by Obama, the "law professor."

Torture, drone murders of babies abroad, drone murders of American citizens, starving of American children with cuts to social programming (genocide), robbing millions of Americans of health insurance while he knowingly lied about it.

Lots of charges. Take your pick.

What's lacking is the initiation of the proceedings. Apparently no one in our one-party fascist political system is willing to kick things off, but Barr will. Pretty sad when you have to look to a scumbag like Barr to do the right thing.
