US Defence Secretary Lloyd Austin visited Kyiv to reassure Ukraine of US support amid concerns that assistance from its biggest ally could waver. The United States has provided over $40 billion of security aid to Ukraine since Russia's invasion and pledged to back Kyiv for 'as long as it takes.' Austin's visit comes as Ukraine announced it had pushed Russian forces back from the banks of the Dnipro river, marking a significant advance for Kyiv's forces. Despite opposition from some Republican lawmakers, the US continues to believe that Congress will provide support for Ukraine.
