Special U.S. envoy Steve Witkoff says Russian leader Vladimir Putin agreed to allow the U.S. and Europe to offer Ukraine a security guarantee resembling NATO's collective defense mandate.

The protections that the US and Europe would be able to provide to Ukraine are similar to NATO's collective defense mandate.

Leaders of five European nations, plus the European Commission and NATO, are meeting with presidents Trump and Zelenskyy Aug. 18. Here's who they are.

A group of European leaders joined a U.S. president at the White House seeking an end to the war in Ukraine, in a display not seen in decades.

Zelensky returns to the Oval Office for the first time since his blowup with Trump. This time he is bringing back up.

The leaders dropped everything to travel to Washington to ensure President Trump didn’t force a bad deal on Ukraine. A road map for peace remains elusive.

European leaders may have rushed to Washington ostensibly to throw a protective arm around President Zelensky and head off any repeat of February's Oval Office bust-up. But their real aim is to stop US President Donald Trump threatening long-term European security after his abrupt change of course over how best to end the war in Ukraine.

Donald Trump has told Ukraine to give up hopes of getting back annexed Crimea or joining NATO as he prepares to host President Volodymyr Zelensky and European leaders in Washington on Monday to press Kyiv into accepting a peace deal with Russia.
