US shipments of weapons into Ukraine were briefly paused in recent days before resuming over the weekend as the Trump administration debated its policy towards Kyiv, according to four people briefed on the matter, Reuters reports.

Shipments restarted after the White House pulled back on its initial assessment to stop all aid to Ukraine, two of the sources said.

There are factions inside the administration that are at odds over the extent to which the US should continue to aid Kyiv's war effort with weapons from US stocks, said one of the people, a US official.

Trump froze arms deliveries to Kyiv in an executive order that suspends US aid to other countries for 90 days, a congressional source told The Washington Post.

The State Department said the executive order primarily applies to the US Agency for International Development (USAID), which has sent tens of billions of dollars to Ukraine as part of the US government’s budget support for humanitarian and development assistance.

The US Department of Defense said military aid to Ukraine is not subject to the restrictions imposed by Trump’s order.

Ukrainian President Volodymyr Zelenskyy also said Trump’s order does not apply to military aid and only affects humanitarian programs. However, it is unclear whether the Trump administration will officially recognize the suspension and subsequent resumption of arms supplies to Ukraine.

According to the State Department, the US has provided Kyiv with $66 billion in military assistance since the start of Russia’s large-scale invasion in Ukraine until early 2025, and almost $70 billion since 2014. Zelenskyy has estimated the amount of arms Ukraine has received at about $76 billion.

Trump, in turn, announced the provision of $200 billion in weapons. Also, he announced that he was preparing to sign an agreement with the Ukrainian authorities, under which Kyiv would receive American aid in exchange for rare earth metals.
