North Korea says it's holding up part of its end of the bargain President Donald Trump struck with Kim Jong-un in Singapore last month.

The U.S. is aiming to get a full declaration of North Korea's nuclear capabilities, while North Korea is angling for some sort of declaration of peace from the U.S.
