‘Punishable by DEATH’: Trump threatens Democrats with sedition charges

A red line for military members

The Uniform Code of Military Justice makes it illegal for service members to willfully disobey the orders of a superior officer.

But such orders are only lawful if they do not run “contrary to the Constitution, the laws of the United States or lawful superior orders”. An order that is “beyond the authority of the official issuing it” is also considered unlawful.

As a result, it is widely understood under US law that soldiers and service members have an obligation to reject orders they understand to be illegal.

In a stitched-together statement featuring the voices of several Congress members, including Senator Mark Kelly of Arizona and Senator Elissa Slotkin of Michigan, the Democrats appeal to military and intelligence workers to stand up to illegal demands.

“You must refuse illegal orders. No one has to carry out orders that violate the law or our Constitution,” the Democrats said in their collective statement.

“We know this is hard, and that it’s is a difficult time to be a public servant. But whether you’re serving in the CIA, the Army, the Navy, the Air Force, your vigilance is critical.And know that we have your back.”
