Retired Adm. Mike Mullen, former chairman of the Joint Chiefs, said on ABC'S "This Week" that nuclear war has become "more probable than it used to be. And it scares me to death, quite frankly."
Mullen also said he has concerns about the fact that generals have taken such high-ranking and high-profile roles in the Trump administration, and that he was disappointed that John Kelly has shown he'll be "supportive of the president no matter what."
