President Joe Biden is under increasing bipartisan pressure to ease restrictions on Ukraine's use of U.S.-supplied long-range weapons against Russian targets. Senators, including Democratic Foreign Relations Committee Chairman Ben Cardin, argue that recent Russian attacks necessitate a change in policy to enable Ukraine to defend itself more effectively. While the Biden administration is reportedly working on a plan to expand Ukraine's targeting options, concerns over escalating the conflict have led to cautious deliberations. U.S. Secretary of State Antony Blinken's recent discussions in Kyiv with British Foreign Minister David Lammy have highlighted the urgency of the situation, but no policy changes have yet been announced. Biden indicated that the administration is close to an agreement regarding long-range weapon supplies, although technical issues may delay deliveries. The request for greater military support comes amidst escalating violence and civilian casualties in Ukraine.
