Retired Lt. Gen. Dan “Razin” Caine, President Donald Trump‘s pick to become the highest-ranking military officer, pledged to lawmakers that, if confirmed, he would remain apolitical and provide his best advice to senior leaders.

Dan Caine, a retired Air Force lieutenant general, committed Tuesday to serving as a nonpartisan leader who would give unvarnished military advice and always “strive to do the right thing” if confirmed as the next chairman of the Joint Chiefs of Staff.

The nominee to become the highest-ranking U.S. military officer sought to reassure Democratic lawmakers on Tuesday that he would not become a "yes man" for President Donald Trump if confirmed, after being plucked from retirement and relative obscurity.
