Some conservative members of Donald Trump's "Make America Great Again" movement have reacted angrily to the president's plans to sell weapons to Nato, arguing it is a betrayal of his promise to end US involvement in foreign wars.

U.S. Ambassador to NATO Matt Whitaker joins the ‘Brian Kilmeade Show’ to discuss President Donald Trump’s updated strategy for the Russia-Ukraine war and what it could mean for the path to peace.

Pentagon officials said details were still being worked out, and experts doubted Mr. Trump’s threat of huge tariffs for Russian trading partners.

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

Ivo Daalder, a senior fellow at Harvard Belfer Center, says that President Donald Trump realizes that he needs to change course because the Russian leader has been playing him "for years."

As Trump demands a deal to end the Ukraine war in 50 days, Russia's deputy foreign minister says "demands, especially ultimatums, are unacceptable."

U.S. President Donald Trump's Ukraine envoy Keith Kellogg began talks in Kyiv on Monday on security and sanctions against Russia. That's a day after the U.S. president said he would send Patriot air defence missiles to Ukraine.

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.
