I'm not sure I see the point in this, because I presume their access to the investigation is far more limited than the one of the special council.
I guess there's some strategic value to having federal charges as well, but I don't expect anything of importance to come from this.
Dems still trying to milk this dead cow? This russian collusion investigation is done, and won't go anywhere.
Only the one handled by the Republicans. The special council's investigation is still very much ongoing, and keeps resulting in more and more guilty please and charges in regards to Trump Campaign/Trump Administration members, as well as a number of Russians.
