The change in policy is being considered after Russia placed weapons across the border from northeastern Ukraine, The New York Times reports.
US officials are considering letting Ukraine strike Russia with US weapons, The New York Times reports.
Ukraine says it's necessary to fight cross-border attacks.
But fears of crossing Russia's red lines have long made the US hesitate.
The US has barred Ukraine from striking targets in Russian territory with its arsenal of US weapons.
But that may be about to change. The New York Times on Thursday reported that US officials were debating rolling back the rule, which Ukraine has argued severely hampers its ability to defend itself.
The proposed U-turn came after Russia placed weapons across the border from northeastern Ukraine and directed them at Kharkiv, the Times reported, noting that Ukraine would be able to use only non-American drones to hit back.
The Times reported that the proposal was still being debated and had yet to be formally proposed to President Joe Biden.
