Not sure if anyone pointed this out yet:

[RR] recuse/fired who has direct oversight of Mueller?

Noel John Francisco (born August 21, 1969) is an American attorney and the current Solicitor General of the United States in the Donald Trump administration. He is the first Asian American confirmed by the United States Senate to hold the position.

With the resignation of Rachel Brand on February 8, 2018, Francisco became the third-ranking official in the Justice Department; he would be in charge of the Mueller investigation should the second-ranking official, Rod Rosenstein recuse himself, quit, or be fired. [16]

Should Rosenstein step down now, Solicitor General Noel Francisco would take over the probe, not Panuccio.
