In the 2016 race for the White House, leading Republican Party establishment members met in Washington, D.C., Thursday to continue efforts to try to block a Donald Trump nomination. Led by RedState.com founder Erick Erickson, the group is calling for a unity ticket that could prevent Trump from winning the 1,237 delegates he needs to secure the nomination outright. This comes as the chair of the Joint Chiefs of Staff, General Joseph Dunford, described some of Donald Trump’s military proposals as illegal. Speaking to the Senate Armed Services Committee Thursday, Dunford answered questions from South Carolina Senator Lindsey Graham, who did not mention Trump by name but asked about tactics he has proposed.

Sen. Lindsey Graham: “What effect, if any, would this have on the war fighter if we started telling our men and women in uniform to intentionally target civilian noncombatants and engage in techniques such as waterboarding or more extreme forms of interrogation?”

Gen. Joseph Dunford: “You know, our men and women—and we ought to be proud of it—when they go to war, they go to war with the values of our nation. And those kind of activities that you’ve described are inconsistent with the values of our nation. And quite frankly, I think it would have an adverse effect. There’s many adverse effects it would have, one that would be on the morale of the force. And frankly, they would—what you’re suggesting are things that actually aren’t legal for them to do anyway.”
