Washington (CNN)Secretary of Defense James Mattis said Tuesday that he believes it is in US national security interest to remain in the Iran nuclear agreement despite repeated hints from President Donald Trump that he is inclined to scrap the deal.

During a hearing before the Senate Armed Services Committee, Sen. Angus King asked Mattis: "Do you believe it is in our national security interest at the present time to remain in the (Joint Comprehensive Plan of Action)? That is a yes or no question."
Mattis replied, "Yes, senator, I do."
