Just sptballing here, but Page D-4 of the Mueller report references to Gregory Craig and another name that is redacted. It appears that both work at the same law firm, Skadden, Arps, Slate, Meagher & Flom LL, and may have acted together.

Gregory Craig left the firm immediately after Paul Manafort was indicted. Craig's replacement was Robert Bauer.

Robert Bauer

In November 2009, he was named to take over the duties at the firm

White House Counsel,[3] upon the resignation of Gregory Craig.[4] Bauer was President Obama's personal attorney and the general counsel of the Obama for America presidential campaign prior to his appointment as White House Counsel. He has also previously served as the general counsel to the Democratic National Committee,[5] and had advised President Obama since Mr. Obama came to Washington, D.C. in 2005 as U. S. Senator.[6]

He also writes articles that help with the cheer leading for congress to keep investigating trump.
