"This shadow government of political appointees with the title of senior White House adviser is embedded at every Cabinet agency, with offices in or just outside the secretary's suite. The White House has installed at least 16 of the advisers at departments including Energy and Health and Human Services and at some smaller agencies such as NASA, according to records first obtained by ProPublica through a Freedom of Information Act request. These aides report not to the secretary, but to Rick Dearborn, the White House deputy chief of staff for policy, according to administration officials. A top Dearborn aide, John Mashburn, leads a weekly conference call with the advisers, who are in constant contact with the White House. The aides act as a go-between on policy matters for the agencies and the White House. Behind the scenes, though, they're on another mission: to monitor Cabinet leaders and their top staffs to make sure they carry out the president's agenda and don't stray too far from the White House's talking points, said several officials with knowledge of the arrangement."
Keith's note: FYI Rick Dearborn used to work for Sen. Jeff Sessions (R-AL) and it is the Alabama mafia inside the Trump Administration that is holding up the naming of a new NASA Administrator (among other things).
