For more than two months, the FBI has been rounding up and charging hundreds of Trump-incited insurrectionists who, in hopes of preventing the Congressional certification of Joe Biden's Electoral College victory last November, stormed the U.S. Capitol on January 6th.

But a number of key questions remain wholly unanswered following the unprecedented attack on our very system of representative democracy. Central to several of those questions is Donald Trump's own, personal, behind-the-scenes machinations to help instigate the uprising and, perhaps, prevent the deployment of the military to help quell the rebellion he encouraged.

The March 3rd Senate committee testimony of Major General William Walker, Commander of the D.C. National Guard, describing a seemingly inexplicable delay in authorization for his troops to provide relief to the U.S. Capitol under siege, underscores the need to determine whether there is a connection between Trump's post-election November 2020 purge of the top civilian leadership at the Department of Defense (DoD) and the January 6th assault.

The purge at the Pentagon began two days after media outlets called the Presidential Election for Joe Biden, when Trump fired Secretary of Defense Mark Esper. Within days, four senior DoD officials either resigned or were fired and replaced by what CNN characterized as "conspiracy theorists and Trump loyalists." Christopher Miller became the Acting Secretary of Defense. Kash Patel, who had previously worked for the disgraced Rep. Devin Nunes (R-CA) on the House Intelligence Committee, was appointed to serve as Miller's Chief-of-Staff.

While one Pentagon official described the November purge as "scary", "unsettling" and the moves one would expect from a "dictator", CNN noted in its contemporaneous account that "no one at the Pentagon has an understanding as to what the grand plan is."

Walker's testimony before the Senate Rules and Homeland Security Committees earlier this month, together with other publicly known evidence, points to a distinct likelihood that, once it became clear he couldn't rely upon the U.S. military to carry out a coup, Trump's "grand plan" entailed a stand-down of the D.C. National Guard while his "personal army", an incited mob of white supremacists, stormed the Capitol on January 6...

Acting Defense Secretary Christopher Miller --- and every civilian and sworn member of the U.S. military under Miller's chain-of-command --- has a legal duty, under the Uniform Code of Military Justice, to refuse to carry out an unlawful order to take part in a military coup that is designed to prevent the peaceful transfer of power to the duly elected 46th President of the United States on January 20, 2021. That duty holds even if the order to carry out that military coup is issued by the current Commander in Chief.

This is not an abstract concern.

Recall that the increasingly desperate Donald Trump previously discussed with the disgraced and recently pardoned, former National Security Advisor, Lt. General Michael Flynn, the possibility of utilizing the military to facilitate a re-do of what U.C. Irvine Law Professor Rick Hasen described as a "decisive" electoral victory for his opponent, Joseph R. Biden.

The prospect that Trump would dare to issue an unlawful coup order was driven home by the fact that all ten living former Secretaries of Defense found it necessary to publish an ominous Washington Post editorial on Sunday that they directed to Miller. With his subordinates, Miller has failed to fully cooperate with the transition, according to President Elect Biden.

The former Secretaries of Defense not only admonished Donald Trump's newly placed Acting Secretary of Defense that he had a duty to facilitate the transition, but also issued a stark warning: "Civilian or military officials who carry out [efforts to involve the U.S. military in the election] would be accountable, including facing criminal penalties, for the grave consequence of their actions on our republic."

The potential for such an unlawful order is underscored by the fact that the former Secretaries of Defense, who signed off on the op-ed, included Mark Esper. He was fired by Presidential Tweet on November 9 --- two days after the networks called the election for Biden. While we don't know precisely what Trump may have conveyed to Esper, there can be no doubt but that Esper, more than any other former Secretary of Defense, is acutely aware of Trump's post-election state of mind.

The word needs to go out, not only to Miller's subordinates and to high-ranking members of the military, serving at the Pentagon, but also to everyone who wears the uniform. You must not obey an unlawful order to carry out a military coup.
