CBS News reported the information, citing diplomatic sources.The potential funding, insiders say, may be meant as a message to Moscow following what Kyiv described as the largest drone assault since the full-scale invasion began in 2022. “Putin is not treating human beings right. He's killing too many people," Trump told reporters during a Cabinet meeting Tuesday. "So we're sending some defensive weapons to Ukraine, and I've approved that.”Earlier this week, Trump hinted at sending more aid just days after his administration paused some shipments. A White House official described the pause as part of a broader review of global arms transfers.The funding source remains unclear, but officials told CBS News Trump could tap into $3.85 billion in leftover presidential drawdown authority or potentially redirect up to $5 billion in frozen Russian assets — powers neither he nor President Biden have used so far.Trump has been critical of U.S. spending on Ukraine in the past and has pushed for peace talks. He’s also clashed with Ukrainian President Volodymyr Zelenskyy, including a heated Oval Office meeting in February that led to a temporary aid freeze.Still, Trump now appears to be leaning on NATO to do more. “We're sending weapons to NATO, and NATO is paying for those weapons, 100%,” he told NBC News.Diplomatic sources say Trump recently discussed Ukraine aid with NATO Secretary-General Mark Rutte, focusing on European allies buying U.S.-made arms. Secretary of State Marco Rubio confirmed Europe would need to purchase certain weapons from the U.S., saying, “At the end of the day, some of the systems that Ukraine requires are systems that Europe doesn't make. They would have to purchase them from the United States.”
