The top Republican on the Senate Foreign Relations Committee said North Korea's announcement that it is suspending nuclear testing shows that Kim Jong Un has “learned about public relations.” Sen. Bob Corker, R-Tenn., told ABC News Chief Anchor George Stephanopoulos on "This Week" Sunday that he is “glad” President Donald Trump is planning to meet with the North Korean leader, but added that “all of us look at this with great caution and skepticism.” “Obviously, Kim Jong Un has learned about public relations and is setting it up well" for himself for the talks by announcing the suspension of nuclear and missile tests, Corker said. According to state TV, Kim said the country had "verified the completion of nuclear weapons" and that now "the Party and our nation will focus all its efforts towards socialist economic development.”
