KYIV, Ukraine (AP) — U.S. President Donald Trump’s special envoy Keith Kellogg said in Kyiv on Monday that officials are “working very, very hard” on efforts to end the three-year war between Russia and Ukraine, as a lack of progress fuels doubts about whether a peace settlement could be on the horizon.

South Korea has long come under targeted criticism from Trump, who has called it a "money machine" that takes advantage of American military protection.

Trump says he has a good relationship with Kim Jong Un and expects to meet 'someday' ahead of White House summit with South Korea's president Lee Jae Myung.
