(Snip) As SWC notes:
Contrary to popular belief, the FBI has not been sitting on its hands all week while evidence of suspicious activity has been developing in multiple locations across the country.
So, Barr at that point knew that the FBI was doing its job. But then it turned out that that wasn't the only roadblock for investigators. It's entirely possible that Barr may not initially have been aware that Pilger was blocking any substantive action on the allegations that the FBI (and probably USAs) was/were receiving. When Barr learned of this, he took action. As SWC explains:
What happened today, and what prompted Pilger to "quit" was that AG Barr said to US Attorneys – "If you have substantial allegations of election fraud in your district, you have authority to investigate that." Basically, Barr cut Pilger and Election Crimes Branch out of the picture as "gatekeepers" to starting investigations in places like Philadelphia, Milwaukee, Detroit, and Atlanta.
It's a bit like federalism in action within DoJ, with authority being devolved to the local judicial district level. But you and I would never have known what was behind Barr's action without insider knowledge of Election Branch procedures. So, with one stroke of the pen Barr has broken up the logjam that obstructionists at DoJ (protected by civil service laws) had constructed. (snip)
