Transcript for Trump, Abe agree to increase pressure on North Korea

Also this morning we are following new developments out of Washington. Overnight president trump spoke to Japan's prime minister about tensions with North Korea in the wake of that missile launch. President Putin has ordered the U.S. To cut 755 members of their diplomatic staff in Russia. This comes as president trump's new chief of staff, retired general John Kelly, the secretary of homeland security, starts his new role as white house chief of staff this morning and replaces reince Priebus who was forced out last Friday. Much more on that in just a moment but first we want to get to the U.S. Response to north Korea's missile test, its most powerful yet. Where it could reach major U.S. Cities. Martha Raddatz has the very latest on this. Good morning. Reporter: Good morning, Amy. There's no question this is one of the most serious challenges the trump administration is facing.
