All 10 living former defense secretaries: Involving the military in election disputes would cross into dangerous territory

Ashton Carter, Dick Cheney, William Cohen, Mark Esper, Robert Gates, Chuck Hagel, James Mattis, Leon Panetta, William Perry and Donald Rumsfeld are the 10 living former U.S. secretaries of defense.

As former secretaries of defense, we hold a common view of the solemn obligations of the U.S. armed forces and the Defense Department. Each of us swore an oath to support and defend the Constitution against all enemies, foreign and domestic. We did not swear it to an individual or a party.
