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.

On Monday, Trump said that Russia's failure to reach a negotiated settlement with Ukraine within 50 days would lead to his administration imposing a 100% tariff rate on Russian imports as well as what he called "secondary tariffs" on countries that have continued to do business with Moscow.

As President Donald Trump hardens his position toward Moscow and seeks new ways to bring its war in Ukraine to an end, he says he isn’t looking to deliver Kyiv longer-range missiles that could strike targets deeper into Russia.

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

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.

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