Blinken: Biden ordered North Korea policy review

U.S. Secretary of State Antony Blinken discussed North Korea's nuclear arsenal in an exclusive interview with NBC News Today. Blinken told NBC Chief Washington Correspondent Andrea Mitchell that North Korea is a "growing problem" that "has gotten worse across administrations."

Blinken said the U.S. President Joe Biden has instructed him to review U.S. policy toward North Korea, "to make sure that we're using the most effective tools to advance the denuclearization of the Korean peninsula."

He added that those tools could include additional sanctions, coordination and cooperation with allies and partners, and diplomatic incentives.
