WHITFIELD: North Korea says it now has missiles that can hit some of the biggest cities in America, and experts agree. Analysts say Friday's test missile is more advanced than the one launched earlier this month, traveling 2,300 miles high for a distance of 621 miles. North Korean Dictator Kim Jong-un says that puts the whole U.S. mainland in range, and at least one analyst says if the missile were fired at a flatter trajectory, North Korea could strike anywhere from Los Angeles to Chicago. CNN's Kristie Lu Stout is joining us live now from Tokyo. So, Kristie, how is the U.S. responding to this latest test?</s>KRISTIE LU STOUT, CNN CORRESPONDENT: Well, Fredricka, the United States was quick to condemn this latest test along with its allies in the region. And we've heard that statement from the U.S. Secretary of State Rex Tillerson who pointed the finger of blame squarely at Russia and China for being the key economic enablers of North Korea's weapons programs. Of course we know that that U.S. new package of sanctions was just passed by the U.S. Senate. It's now on President Donald Trump's desk awaiting for him to sign that off. If he does sign that off, that would level sanctions targeting Chinese institutions that do business with North Korea, so putting the pressure on North Korea directly that way. But this is a new reality here that everyone in the region is still grappling with, the fact North Korea tested a second intercontinental ballistic missile. The timing was expected time to coincide with the anniversary of the armistice. What was not expected is the amount of progress it signals. Back to you.</s>WHITFIELD: All right, Kristie Lu Stout, thank you so much for that. All right, it is not the most visible role in the White House, but it could be one of the most crucial. Our next guest explains how a chief of staff is more than a gatekeeper and can alter the course of a presidential administration.
