The Kremlin denied Tuesday that it was holding up President Donald Trump’s latest push to end the war in Ukraine, and insisted it had not changed its demands ahead of possible talks. Trump had announced that Russia and the United States' top diplomats would meet this week, with his own summit with Vladimir Putin to follow in Budapest, Hungary.

There are no plans for President Donald Trump and Russian President Vladimir Putin to meet "in the immediate future," a White House official said on Tuesday -- calling off a summit that was expected in Hungary in the coming weeks.

Trump called a proposed tunnel from Russia to Alaska 'interesting' and said he would 'have to think about that.'
