But Twitter's article says that the former widespread resigned, and his nickname preceded Trump's presidency.
It follows final week's explosive confrontation, which noticed Twitter fact-check two of President Trump's tweets and label any other as glorifying violence.
The state-of-the-art disagreement was once precipitated by using a strongly-worded announcement issued by way of General Mattis ultimate night, in which he criticised the president's managing of the protests that observed the killing of George Floyd.
Gen Mattis described Donald Trump as "the first president in my lifetime who does no longer attempt to unite the American human beings - does now not even fake to try. Instead, he tries to divide us."
The president fired returned shortly in a tweet pronouncing that the one factor he and predecessor Barack Obama had in frequent was once "we each had the honour of firing Jim Mattis, the world's most overrated general. I requested for his letter of resignation and felt true about it".
"His nickname used to be 'Chaos', which I did not like, and modified it to 'Mad Dog'," he added.
Twitter later posted what it calls a Moment, a precis of a information story that you can see when you press the platform's search button. It has additionally been promoted inside the What's Happening field that seems on Twitter's website.
The article says that "Mattis resigned from the position... after the administration determined to withdraw US troops from Syria", and attributes the reality to a file by means of the Associated Press information agency.

It used to be on 20 December 2018 that Gen Mattis introduced his resignation, high quality from 28 February 2019.
A livid Mr Trump then introduced his defence secretary was once going from 1 January and cited he'd surely fired him. So you ought to at least argue that, as in many cases, there is a blurry line between a resignation and a firing.
