Trump said after a call last week with Putin that he was unhappy with Russia’s president and “I don’t think he’s looking to stop” the war. Then, speaking at the start of a dinner he hosted for Israeli Prime Minister Benjamin Netanyahu at the White House on Monday night, Trump said, “I’m not happy with President Putin at all.”

Former U.S. Ambassador to Ukraine Bill Taylor joins NewsNation to discuss the sharp shift in President Trump’s stance toward Russia. Though he once called Vladimir Putin a "great guy," Trump is now sending more weapons to Ukraine and weighing tough Senate-backed sanctions against Moscow.

President Donald Trump said on Tuesday he had approved sending U.S. defensive weapons to Ukraine and was considering additional sanctions on Moscow, underscoring his frustration with Russian President Vladimir Putin over the growing death toll in Russia's war with Ukraine.
