Hysterical Hollywood celebrities hit the panic button Wednesday following news that Attorney General Jeff Sessions resigned.

“Trump fires his attorney general. We all know where this is heading. Trump will fire the Special Prosecutor & have all his evidence & files either locked up or shredded. Lame-duck House Repubs will destroy anything that could lead to Trumps impeachment. DEMS! GET READY TO FIGHT!” Michael Moore said.
