Trump won't say Kim Jong-un's okay; waffles on North Korean Supreme Leader's health again

US President Donald Trump on Thursday told journalists he understood "what's going on" with Kim Jong Un, as speculation about the North Korean leader's health continued to build.

Kim has not been seen in public for a while and even though South Korea has said it believes that he is alive and in control, rumours pour in daily suggesting he may be very ill, or possibly even dead. Asked if he was able to provide an update, Trump said he hoped "everything is going to be fine".

"I do understand the situation very well", the president continued, but stressed that he just could not talk about it "right now".
