North Korean leader Kim Jong Un inspected a facility that produces nuclear material and called for bolstering the country’s nuclear fighting capability, state media reported Wednesday, as the North looks to increase pressure on the United States following the inauguration of President Donald Trump.

U.S. President Donald Trump said in an interview broadcast on Thursday that he plans to seek to engage North Korean leader Kim Jong Un anew after the two men developed a working relationship in Trump's first term.

President Donald Trump said on the 23rd (local time) that he would attempt diplomacy again with North Korean Chairman Kim Jong Un. In a Fox News interview released that day, President Trump responded "I will" when host Sean Hannity asked, "Will you reach out to him again?"
