Is this evidence that the FBI at best tried to setup Trump or at worst tried to laid the ground for his removal from office?

I was scrolling thru my feed this afternoon (got a day off) and I ran across this piece from Daily Caller.

John Ratcliffe, the director of national intelligence, on Thursday sent Congress a newly declassified memo related to an FBI briefing given to Donald Trump and Michael Flynn in August 2016 that was used as cover to collect evidence for the Russia probe.

Joseph Pientka, a supervisory special agent, wrote the memo following his Aug. 17, 2016 briefing to Trump, Flynn and Chris Christie, a Trump campaign adviser.

Pientka, who was one of the top agents on Crossfire Hurricane, developed the briefing materials in coordination with Peter Strzok, the lead investigator on the Trump-Russia probe. Kevin Clinesmith, an FBI lawyer found to have altered an email related to Carter Page, also worked on the plan to use Pientka in the briefing, according to the memo.

Here.

Its a bit involved but the upshot is clear.  The FBI seems to have been after Trump since day one.

Dude has done silly stuff since being elected and he has definitely said stuff that has raised eyebrows but Presidents come and go.  The FBI is here to stay and they seem to have had a finger on the scale of national politics.

Should we be concerned?
