It’s not a criminal investigation of Donald Trump and his presidential campaign, because no specified criminal charges were ever made and subsequently investigated
If the GW Bush administration had the CIA director and people in the FBI and Department of Justice spying on and investigating the Obama campaign throughout 2008 for unspecified illegal acts that were still unspecified two years later (no proof of anything illegal, just “connect the dots”), I’m certain the Democrats would not have been saying the Obama administration exceeded its authority by investigating alleged malfeasance and abuse of power by individuals in the Bush administration.
