There is no more sacred room for military officers than 2E924 of the Pentagon, a windowless and secure vault where the Joint Chiefs of Staff meet regularly to wrestle with classified matters. Its more common name is “the Tank.” The Tank resembles a small corporate boardroom, with a gleaming golden oak table, leather swivel armchairs and other mid-century stylings. Inside its walls, flag officers observe a reverence and decorum for the wrenching decisions that have been made there.

This Abridge News topic aggregates four unique arguments on different sides of the debate. Here are the quick facts to get you started:

THE QUICK FACTS

President Trump sought to enlist then-Secretary of State Rex Tillerson in the fall of 2017 to work with Rudolph W. Giuliani to help stop the prosecution of a Turkish Iranian gold trader represented by the former New York mayor, according to people with knowledge of the request.

On Monday, Rex Tillerson, the departing Secretary of State, cut short a visit to Africa to fly back to Washington. Before he left, he remarked that the nerve-gas attack recently carried out on a former Russian spy in Salisbury, England, was a “really egregious act,” but he also said it wasn’t entirely clear who was responsible. Later on Monday, though, the State Department issued a statement in which Tillerson expressed his “full confidence” in the British government’s assessment that the Russian state was almost certainly the culprit.

Secretary of State Rex Tillerson was fired via Twitter after returning from an Africa trip during which he was out of the loop on North Korean talks and contradicted the White House position on Russia's responsibility for poisoning a former double agent in the United Kingdom.

Popularly on social media, and even among a few foreign-policy mandarins, I’ve seen the theory floated that Donald Trump may have fired Secretary of State Rex Tillerson because Tillerson suggested Russia was behind the murder of an ex spy in the United Kingdom.

The world learned that President Trump fired Secretary of State Rex Tillerson by a tweet. In doing so, the president broke a cardinal break-up rule: When breaking up, do it in person. It’s the decent thing to do.

President Trump announced the firing of Secretary of State Rex Tillerson Tuesday morning but according to the State Department, Tillerson didn't see it coming and hasn't spoken directly to the President. From Fox News' Rich Edson.

Sacked US Secretary of State Rex Tillerson has warned of Russia's "troubling behaviour and actions" in a parting statement after being fired by President Donald Trump.
