President Donald Trump continued his war of words with Kim Jong-un early Friday morning, calling the North Korean leader a "madman" and stating he "will be tested like never before!"
He then attacked the Russia investigation, Facebook and Hillary Clinton.
On Thursday, Kim Jong-un referred to Trump as a "frightened dog," before stating: "Far from making remarks of any persuasive power that can be viewed to be helpful to defusing tension, he made unprecedented rude nonsense one has never heard from any of his predecessors. A frightened dog barks louder."
Unsurprisingly, Trump used Twitter to respond in kind, tweeting, "Kim Jong Un of North Korea, who is obviously a madman who doesn't mind starving or killing his people, will be tested like never before!"
Tensions between the two countries have grown since Trump threatened to destroy North Korea during a speech to the United Nations earlier in the week, leading North Korea to float the idea of testing a hydrogen bomb over the Pacific Ocean as a show of strength.
Trump later turned his focus on the Russia investigation, specifically calling out Facebook.
