Secretary of State Rex Tillerson said Saturday the U.S. government has direct lines of communication to North Korea over its continued nuclear and missile tests.

“We are probing, so stay tuned,” Tillerson told reporters when asked how he could start a dialogue with North Korean leader Kim Jong Un. “We ask, ‘Would you like to talk?’ We have lines of communications to Pyongyang. We’re not in a dark situation, a blackout. We have a couple, three channels open to Pyongyang.”
