WASHINGTON - President Donald Trump has put North Korea "clearly on notice" that he will not tolerate certain actions but would not telegraph U.S. moves in advance, a White House spokesman said on Tuesday.
Spokesman Sean Spicer was responding to a question about a Trump Twitter post earlier in the day that read: "North Korea is looking for trouble. If China decides to help, that would be great. If not, we will solve the problem without them! U.S.A."
