Sen. Graham says U.S. is "long ways away from an agreement" with North Korea
Republican Sen. Lindsey Graham of South Carolina joins "CBS This Morning" from Washington to discuss why the historic summit between President Trump and North Korean leader Kim Jong Un is an "agreement in principle." He also says he doesn't mind U.S.-South Korea military exercises being put on hold, but "violently" objects to withdrawing troops from the Korean Peninsula. "China is trying to play President Trump though North Korea," Graham said.
