UNITED STATES — According to Politico, former Marine general James Mattis will divest all of his stock in General Dynamics, resign from the board of directors, and recuse himself from all matters involving the company for a period of one year after taking office.

The report, citing an ethics agreement dated Jan. 5, says that all of that would have to happen within 90 days if confirmed by the Senate. He would also resign from the Board of Directors at the Hoover Institute at Stanford University if confirmed. He has already resigned from the boards of several high-profile companies,

General Dynamics is the fourth-largest Pentagon contractor, and Mattis joined the board of directors in 2013 after retiring from the Marine Corps.

In order to take his position, both the House of Representatives and the Senate will have to pass an exception to the law that says that a person must wait seven years from when they leave the military before taking the job as the head of the Pentagon.

His confirmation hearing before the Senate Armed Services Committee is scheduled for Tuesday, followed by a vote by the full Senate. If confirmed, he will take office when Trump is inaugurated on Jan. 20.
