Trump on Monday said the United States would ship "billions of dollars' worth" of military equipment to NATO members, paid for by the alliance, to be handed over to Ukrainian forces battling grinding Russian advances. Trump had earlier this month suggested NATO would "100 percent" pay for U.S. weapons, which would be sent to Ukraine.

Ukrainian President Volodymyr Zelenskiy also held talks with a U.S. envoy on Monday on increasing weapons production and arms purchases.

Donald Trump’s remarks on Ukraine on Monday were far from the biggest announcement the US president could have made.

President Donald Trump has softened his stance on NATO. He once called the Western alliance "obsolete." Now, he says, it's the "opposite of that."

Trump agrees to sell billions in US arms to NATO countries including Germany, Finland and Denmark and others for quick distribution to Ukraine, following his ultimatum to Putin on peace talks.

President Donald Trump made an announcement Monday aligning him more firmly with Ukraine’s defense against Russia’s invasion than ever before.

During his campaign, Trump said bringing a quick end to the war was a top priority and that helping Ukraine was a waste of US taxpayer money.

President Trump is hosting NATO Secretary General Mark Rutte at the White House on Monday as the U.S. agrees to sell new and more weapons to Europe and Ukraine.
