North Korea's reaction to Pence was 'last straw' for Trump

North Korea's reaction to comments by U.S. Vice President Mike Pence were the "last straw" that led the White House to cancel President Donald Trump's planned summit with North Korean leader Kim Jong Un, a White House official said on Thursday, according to Reuters.

North Korea's vice foreign minister called remarks by Pence about North Korea stupid and suggested the two countries could either meet for a summit or for a nuclear showdown.
