Russian President Vladimir Putin is stalling over a ceasefire. Meanwhile, Trump has changed his mind about sending weapons to Ukraine.

Sitting in the Oval Office with NATO Secretary-General Mark Rutte, and apparently fed up with being slow-walked by Russian President Vladimir Putin, Trump threatened the Kremlin with tough tariffs if it doesn't make a deal to end the war within 50 days. But perhaps more important was Trump's shift on weapons.

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.
