According to The Daily Beast, however, a comment from Chief of Staff John Kelly suggests that the context in which Tillerson found out about his firing was far from normal. Secretary of State Rex Tillerson was just unceremoniously ousted.
Most likely to exit, after McMaster, were Attorney General Jeff Sessions and Press Secretary Sarah Sanders, with odds of 7/4 and 6/1, respectively.
Washington is braced for a shake-up, with #firingfriday circulating on social media and aides admitting privately that no one knew what Mr Trump had planned.
Sanders looked to tamp down the possibility of McMaster leaving the White House, though, telling reporters that she spoke directly to Trump about the national security advisers' standing.
Kelly also made a point of communicating he's not around for a lot of Trump conversations, so can't be sure what Trump is and is not saying to people in his phone calls. Also Friday, Chief of Staff John Kelly reportedly told an invited bunch of journalists, OTR, that Trump was probably behind the reports of more cabinet shakeup.
In any case, if you thought Tillerson suffered enough public humiliation this week when the president fired him in a tweet, always remember: in this White House it can always get worse.
His economic nationalism became the lynchpin of Trump policies, even as many of his other ideas were rebuffed by policy rivals.
U.S. National Security Adviser H.R. McMaster leaves his office at the end of the day at the White House in Washington, U.S. March 16, 2018.
The president and McMaster have disagreed on a number of issues - including the Iran deal and the US approach to North Korea - and the national security adviser has also clashed with Kelly and Defense Secretary James Mattis, according to the officials.
Mcmaster, a three star general, and President Trump never really gelled.
The newspaper said that Trump is discussing potential replacements for McMaster, but is willing to take his time because he wants to avoid humiliating him as well as to have a successor ready.
Trump's nominee to be the next secretary of state -CIA director Mike Pompeo - is a longtime favorite of the president who has demonstrated rare ability to navigate the West Wing. The president was speaking to friends outside the administration about his frustrations with advisers, Mr Kelly suggested.
