Trump’s decision reportedly impacts over $1 billion worth of weaponry and ammunition that was set to be delivered to Ukraine, which has been under attack by invading Russian forces since February 2022. The U.S. has provided more than $65 billion in military aid to Ukraine during the full-scale Russian assault, according to State Department figures.

The Associated Pressnoted Monday that the U.S. president’s move “comes some five years after Trump held up congressionally authorized assistance to Ukraine as he sought to pressure [Ukrainian President Volodymyr] Zelenskyy to launch an investigation into Joe Biden, then a Democratic presidential candidate.”
