James Mattis is joining The Cohen Group, a business consulting firm founded by Clinton administration Secretary of Defense William Cohen, Politico reports.
Mattis served as President Donald Trump's secretary of defense from January 2017 to December 2018.
“Jim Mattis is a national treasure, a leader known throughout the world for his strategic judgment as well as his unyielding principles,” Cohen said in the announcement.
"We are honored to be working with him, and our clients will benefit from his knowledge and guidance," Cohen added.
Mattis, a retired four-star Marine Corps general, resigned when he determined his views were not “aligned” with Trump.
In an interview Sunday with CBS, Mattis said he intended to serve the full four years but couldn’t move forward as he disagreed with Trump's decision on Syria because "we need to maintain enough influence there that we don't see the same thing that happened when we withdrew from Iraq."
"This is how I saw the strength of America — that we keep our alliances together, and keep them tight," he added.
