President Donald Trump shakes hands with Gary Cohn, Director of the National Economic Council, during a retreat with Republican lawmakers and members of his Cabinet at Camp David in Thurmont, Maryland, January 6, 2018.

A year ago, with an impressive roster of Goldman Sachs alumni on their way to top White House positions, the return of "Government Sachs" was in full swing.

The newly inaugurated President Trump tapped Steven T. Mnuchin as treasury secretary, Gary D. Cohn as director of the National Economic Council and Dina Powell as White House adviser. Ms. Powell later served as both deputy national security adviser for strategy and senior counselor for economic initiatives.
