"And I can tell you who is going to win." Should the secretary of state accept Trump's challenge, Mensa has agreed to host an IQ showdown, the Hill reports. Meanwhile in the rest of the Forbes interview, Trump doubles down on his contention that Tillerson "was wasting his time" in negotiating with North Korean strongman Kim Jong Un, leading his interviewer to question whether "publicly upbraiding" the nation's top diplomat renders him ineffectual. "I'm not undermining," Trump responds. "I think I'm actually strengthening authority." Read These Next New Fox star, 23, misses first day after car troubles.
