Well, according to Jordan there’s lots of investigate because they’ve been bitching about the subpoenas they’d want to send to Pelosi.
The FBI doesn’t investigate everything, nor is everything worth investigating illegal. Obviously this is the case or else there’d have been no need for 8 Benghazi investigations that Republicans had no problem wasting money for.
As for the makeup of the commission; it was going to have 5 Republican appointed members. Now, if the Republicans appoint Trump haters, that’s on them, but they wouldn’t get to complain about anyone else controlling who was on it.
