RUBIO: Mr. President -- first of all, everybody's made this comment already, it needs to be echoed again: you were elected as president of working Americans. And that's why this Labor Day is so meaningful.

For me, personally, this the most meaningful Labor Day of my life, as someone with four jobs. //

Rubio, of course, has taken on a few side gigs to complement his main role leading the State Department (he was the first Cabinet secretary to be confirmed, with his nomination having passed the Senate on Inauguration Day). Here's what else is currently on his resume:

Interim National Security Advisor;
Acting Administrator of the U.S. Agency for International Development (USAID); and,
Acting Archivist of the United States. //

Secretary of Transportation Sean Duffy also moonlights as Interim Director of the National Aeronautics and Space Administration (NASA). Russ Vought is Director of the Office of Management and Budget (OMB) by day and leads the Consumer Financial Protection Bureau (CFPB) by night. And Jamieson Greer does double duty as acting Director of the Office of Government Ethics and acting Special Counsel of the Office of Special Counsel.

A few non-Cabinet-level appointees are also pulling extra weight, with Daniel Driscoll serving as both Secretary of the Army and acting head of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and Todd Blanche holding the positions of Deputy Attorney General and acting Librarian of Congress.
