When I joined the Board in early 2014, after leaving government service as Under Secretary of Defense for Policy, I again swore an oath of office, one familiar to you, that includes the commitment to “support and defend the Constitution of the United States . . . and to bear true faith and allegiance to the same.”

You recited that same oath on July 23, 2019, when you were sworn in as Secretary of Defense. On Monday, June 1, 2020, I believe that you violated that oath. Law-abiding protesters just outside the White House were dispersed using tear gas and rubber bullets — not for the sake of safety, but to clear a path for a presidential photo op.
