Donald Trump has chosen James “Mad Dog” Mattis as his Secretary of Defense. Per the Washington Post:

President-elect Donald Trump has chosen retired Marine Gen. James N. Mattis to be secretary of defense, nominating a former senior military officer who led operations across the Middle East to run the Pentagon less than four years after he hung up his uniform, according to people familiar with the decision.

To take the job, Mattis will need Congress to pass new legislation to bypass a federal law that states secretaries of defense must not have been on active duty in the previous seven years. Congress has granted a similar exception just once, when Gen. George C. Marshall was appointed to the job in 1950.

We wrote about the possibility of Trump adding Mattis to his cabinet several weeks back. Here’s what we said about the possible selection of Mattis and what it might mean:

Note to Barack Obama and the Democrats: This is what a “reset” looks like. The Trump administration is sending a signal to our enemies: No more Mr. Nice Guy.
