Ret. Gen. James Mattis, President-elect Donald Trump's pick for Defense secretary, has ties to General Dynamics that may raise conflict questions.

The retired Marine Corps former four-star general has received stock and option awards as a board member of General Dynamics since August 2013. In 2015, those equity awards exceeded $140,000 in value, and the prior year they topped $112,000. There's also cash compensation given to the board members.
