US President Donald Trump tweeted on Sunday that he told the US Secretary of State not to waste his time trying to negotiate with North Korean leader Kim Jong-un, CBC News reports.
"I told Rex Tillerson, our wonderful Secretary of State, that he is wasting his time trying to negotiate with Little Rocket Man," Trump wrote on Twitter, using his sarcastic nickname for Kim.
Trump's comment came the day after Tillerson disclosed that the United States was directly communicating with North Korea on its nuclear and missile programs but that Pyongyang had shown no interest in dialogue.
"Save your energy Rex, we'll do what has to be done!" Trump tweeted.
