Trump is preparing to send weapons directly to Ukraine, marking the first time he will personally exercise his authority to do so.

NATO itself doesn't send weapons to Ukraine or otherwise own or handle arms — that is done by its 32 member nations — but it does coordinate the deliveries of weapons to a logistics hub in Poland, bordering Ukraine.

The US has $3.86 billion left for Ukraine under the Presidential Drawdown Authority. The last $500 million package was approved by Joe Biden on January 9.
