U.S. Secretary of State Mike Pompeo said there is no timeline for North Korea's denuclearization, but that the U.S. is committed to moving forward at an "expeditious moment".<br /> Speaking to CNN in a telephone interview on Sunday, marking his first two months in office, Pompeo added that the Trump administration will "constantly reassess" whether enough progress is being made to continue negotiations.<br />This contradicts a senior defense official, who said ahead of Defense Secretary Jim Mattis' trip to Asia that Washington will soon set a timeline for North Korea with "specific asks". <br />Pompeo himself had also told reporters the day after the first ever North Korea-U.S. summit on June 12th that Washington hopes to achieve "major disarmament" by North Korea within Trump's current term, which ends in January 2021. <br />
