No. Not yet.
Matthew Whitaker, the acting Attorney General who took over for Jeff Sessions, is now overseeing Robert Mueller’s probe into Russian election meddling. Democrats have referred to his previous statements about the investigation as basis for him to recuse himself.
As long as he doesn’t do anything to hinder the investigation, there’s no reason for him to recuse himself. He won’t be able to subvert the investigation without his actions leaking to the press. He knows it. President Trump knows it.
He will only be acting Attorney General for a maximum of 210 days. He cannot be confirmed to a position that he holds in the interim.
If Democrats were smart, they’d wait for Whitaker to do something detrimental to the investigation before calling for him to recuse himself. But they’re not smart, so making a stink now makes sense to them.
