How many investigations into the dreamed up Russian/Trump election connection?

The House and the Senate each have investigations under way. 

There was an Intel investigation in December.  Directors Clapper (NIA)  and Brennan (CIA) each announced no connection of a Russian connection to the elections via the Trump Campaign. They found no collusion, collaboration or communication between Russia and the Trump campaign. 

It is not known whether the FBI is currently investigating the issue since the FBI does not announce on-going investigations  . . . . . .  as a rule.  

A.G. Jeff Session's has recused himself from any investigations,  in an afternoon announcement on Thursday. 

Democrats are still running around the White House with their hair on fire.  They just do not know what to do when they are not in control.  Kind of funny,  in my humble opinion.
