Trump's moves underline his growing disenchantment with Russian President Vladimir Putin over the lack of progress in U.S.-led efforts to secure a ceasefire.

President Donald Trump confirmed the U.S. is sending Ukraine Patriot air defense missiles to help it fend off Russia’s intensifying aerial attacks.

Sending U.S. Patriots marks a shift for Trump, who had previously refrained from approving new weapons shipments to Ukraine since he returned to the White House. It also comes as U.S. Senator Lindsey Graham announced record levels of U.S. arms would go to Ukraine, dealing a blow to Putin.
