Secretary of Defense James Mattis announced his intention Thursday evening to retire in late February, with President Donald Trump noting that he would name his successor in the coming days.
General Jim Mattis will be retiring, with distinction, at the end of February, after having served my Administration as Secretary of Defense for the past two years. During Jim’s tenure, tremendous progress has been made, especially with respect to the purchase of new fighting….

….equipment. General Mattis was a great help to me in getting allies and other countries to pay their share of military obligations. A new Secretary of Defense will be named shortly. I greatly thank Jim for his service!

Mattis’s announcement ignited a fire of speculation in Washington as to who would replace the most respected member of Trump’s cabinet.

Mattis resigned from the administration over several disagreements with Trump on foreign policy, particularly in light of recent decisions to withdraw U.S. forces from Syria and draw down the U.S. presence in Afghanistan.
Mattis’s resignation letter laid out several areas of disagreement with Trump’s world view noting, “because you have the right to have a secretary of defense whose views better align with yours….I believe it is right for me to step down from my position.”

Sources close to the White House noted that Trump faced a particularly difficult challenge in replacing Mattis given the high level of esteem he held throughout official Washington, and especially on Capitol Hill. Whoever Trump nominates will presumably often be before the House Armed Services Committee, which is slated to be controlled by the Democratic party.

These sources cautioned, however, that Trump appeared particularly emboldened in recent months to follow his own course of action and could buck all expectations, though he will still have to contend with the Senate confirmation of any of his nominees.
- 1. Deputy Secretary of Defense Patrick Shanahan
One source familiar with the president’s thinking on national security affairs noted Trump’s recent penchant for elevating deputies of departed personnel. Trump took this course of action with the departure of EPA Administrator Scott Pruitt. He also elevated Mick Mulvaney to the chief of staff role on a long term “acting” basis, and he is expected to do the same at the Department of the Interior.
Shanahan is a technically proficient deputy defense secretary who joined the Pentagon from Boeing, where he served as an executive for decades. Shanahan also holds the benefit of being confirmed by the U.S. Senate in July 2017 by a 92-7 vote. The overwhelming margin of approval would make it difficult for Democratic lawmakers to mount a campaign against him.
- 2. Former Sens. Jon Kyl or Jim Talent
Two knowledgable sources close to the White House mentioned both former Sens. Jon Kyl and Jim Talent as possible candidates to replace Mattis, though cautioned that discussions are in their absolute infancy.
These sources noted that Kyl’s and Talent’s relationships on Capitol Hill and political knowledge would benefit the president and aid in their own potential confirmations. Both senators also have previous defense experience on Capitol Hill.
Talent’s name was widely mentioned throughout Washington in 2016 after Trump’s victory as a possible secretary of defense. Talent currently serves on the U.S.-China Economic and Security Review Commission and has extensively authored papers on defense policy since losing his senate seat in 2006.
Kyl most recently served in the vacated seat of deceased Sen. John McCain on a temporary basis, but kept to his pledge that he would not stay in the temporary seat past 2018. Kyl served three terms as a senator from Arizona, but left the upper chamber for retirement and some lobbyist work. Kyl developed strong trust with the White House in the previous year when he served as the sherpa on Capitol Hill for Justice Brett Kavanaugh.
- 3. Sens. Lindsey Graham and Tom Cotton
Graham and Cotton have developed strong relationships with Trump on national security, though the particular reasons for Mattis’s resignation complicate their ability to take the job. Both senators have been highly critical of Trump’s decision to withdraw troops from Syria and are seen as defense hawks.
Additionally, Sen. Mitch McConnell is said to have made it known to Trump that he does not want the president to pluck members of his caucus. McConnell and other Republicans are wary of what happened in Alabama during the special election to fill the seat of Jeff Sessions. The loss of Sessions’s seat to a Democrat was heavily felt during the 2018 session of Congress.
