A second meeting between U.S. President Donald Trump and North Korean leader Kim Jong Un will have to wait until after the Nov. 6 midterm elections.

Trump said Tuesday that campaigning for the upcoming polls left him with no choice, after earlier announcing that the White House had narrowed the summit venue to three or four possible locations.

"It'll be after the midterms. I just can't leave now," pool reports quoted Trump as saying as he flew to Iowa for a political rally.
