 Pompeo said North Korea hadn't responded to recent U.S. queries about logistics for the summit.

The summit between President Trump and North Korean leader Kim Jong Un is off. President Trump has canceled this meeting, which had been set for June 12 in Singapore. The U.S. was hoping to reach an agreement on ending North Korea's nuclear weapons program. Secretary of State Mike Pompeo was on Capitol Hill this morning for a Senate hearing, and he read out loud the president's letter to Kim Jong Un canceling the summit.

Pompeo also said North Korea hadn't responded to queries by the United States in recent days involving logistics for the summit. Relations between the two governments had been deteriorating.
