President Donald Trump says his administration has already had “very serious” discussions with Russia about its war in Ukraine and that he and Russian President Vladimir Putin could soon take “significant” action toward ending the grinding conflict.

Ukrainian President Volodymyr Zelenskyy has said excluding his country from talks between the US and Russia about the war there would be “very dangerous.” He’s also asked for more discussions between Kyiv and Washington to develop a plan for a ceasefire.

Donald Trump pledged to end the conflict in Ukraine, but the war has proved tough to solve. Now, he says he'll sanction Russia.
