Sen. Graham: "China is trying to play President Trump though North Korea" After his historic meeting with North Korean leader Kim Jong Un, President Trump said he is ending the "war games" consisting of joint military exercises with South Korea. In this excerpt of his interview with "CBS This Morning," Republican Sen. Lindsey Graham explains why he doesn't mind putting the joint exercises on hold but "violently" objects to withdrawing troops from South Korea. He says China is trying to drive the U.S. out of Asia.
