Breaking: Trump Chooses ‘Mad Dog’ Mattis As Defense Secretary. Here’s What You Need To Know.

According to The Washington Post, President-elect Donald Trump has chosen retired Marine Gen. James N. Mattis, 66, to be secretary of defense. The Post reported the announcement will be made next week.

Mattis will need an exemption from Congress, as he retired less than four years ago, and secretaries of defense must not have been on active duty in the previous seven years. The only time this exemption was granted was in 1959, when Gen. George C. Marshall was appointed by Harry Truman.
