CIA chief Pompeo held secret meeting with Kim Jong-un

CIA Director Mike Pompeo held a secret meeting with Kim Jong-un in North Korea earlier this month in what is believed to be the highest-level meeting between the two countries in nearly two decades.

The "meeting went very smoothly and a good relationship was formed", US President Donald Trump said on Twitter on Wednesday.

US media reported that Pompeo made the trip shortly after being named Trump's pick to replace Rex Tillerson as secretary of state.
