On December 10, 2020, President Trump issued an Executive Order. The Executive Order lists the order of succession of the U.S. military should the Secretary of Defense die, resign or be unable to perform his duties. Interestingly, the Chairman of the Joint Chief of Staffs, General Mark Milley, is not on the list.
One day later, on December 11, 2020, President Trump issued an Executive Order related to Christmas Eve. This year the President is giving all U.S. government employees Christmas Eve off. This holiday applies to all employees of the government except those related to “National Security, Defense or other public need.” This also makes the holiday weekend a four-day weekend instead of three.
