Mattis' Resignation Will 'Leave a Mark' on Trump — CNN's Mike Rogers

US President Donald Trump's decision has prompted the resignation of Defense Secretary Jim Mattis and US envoy to the worldwide anti-IS coalition Brett McGurk. Shanahan was travelling away from Washington when Trump tweeted his decision, and a spokesman for Shanahan declined to comment.

Trump has issued a further series of statements since then criticizing Mattis, saying Mattis did not see a problem with the USA subsidizing the militaries of rich countries, or allowing them to "take total advantage of the U.S. and our TAXPAYERS, on Trade".

The video was recorded December 19, one day before Mattis submitted his scathing resignation letter to President Trump. "I DO, and it is being fixed!" he wrote.

On Sunday, Mr Trump tweeted that Deputy Defence Secretary Patrick Shanahan would take over for Mattis on an acting basis on January 1.

"Since Washington crossed the DE at Christmas in 1776, American troops have missed holidays at home to defend our experiment in democracy", Mattis said in a 20-second video. Pat Ryder. Ryder said Dunford "told them that they're American soldiers, they have a mission to do, and to just get after it". Lindsey Graham, R-S.C., who was there.

Shanahan also has overseen the Pentagon's audit, its development of a new missile defence policy that still has not been released and a fledgling effort to reduce waste in military expenditures. He earned a bachelor's degree in mechanical engineering from the University of Washington, then a master's degree in mechanical engineering as well as an MBA from the Sloan School of Management at Massachusetts Institute of Technology.

Shanahan, a longtime Boeing Co. executive, was nominated for the deputy job in early 2017.

The highly praised Secretary of Defense has a reputation for being tough as a box of hardened nails. For example, when Chuck Hagel was told to resign in November 2014, he stayed in office until Ash Carter was confirmed the following February. "General Mattis is the living embodiment of the Marine Corps motto, semper fidelis, always faithful".

Administration officials said Trump was annoyed by Mattis' resignation letter, which included an implicit criticism of Trump's disregard for allies.

They asked Trump to "not make any final decision for 90 days to allow time to adequately study the impacts of this decision on our partners, our allies and the re-emergence of ISIS and other terror groups, to ensure our nation's strategic interests are secured".

Mattis resigned in protest over Trump's decision to pull all USA troops out of Syria. "Some thought I shouldn't, I thought I should", Trump tweeted Saturday, foreshadowing his displeasure and the Sunday announcement.

The outgoing defense secretary said it was a privilege to have served alongside men and women in the armed forces.

"With me, hit hard instead by the Fake News Media".

When Trump chose to pull USA troops out of Syria, he reportedly ignored the advice of his closest advisers, including Mattis, who had warned the president that ISIS still was still active in the region and that a US withdrawal would ignite chaos.

Mattis's brother, Tom, said the secretary was not angry about being fired early, according to The Seattle Times. "Even if I have get a little bit smaller, we will be okay".
