Ukrainian President Volodymyr Zelenskyy visited London to attend a summit organized by British Prime Minister Keir Starmer with other European leaders. The visit included the signing of a £2.26 billion loan agreement. Discussions focused on strategies for ending the ongoing war in Ukraine and rallying international support for Ukraine's military efforts against the Russian invasion.

President Trump's senior aides and allies criticized Zelenskyy for not showing enough gratitude for U.S. support and for not being open to potential concessions to Russian President Vladimir Putin. Some officials demanded Zelenskyy display more gratitude for U.S. support. Senator Bernie Sanders described calls for Zelenskyy to step down as a “horrible suggestion.”

The discussions occurred amidst broader concerns about the relationship between the U.S. and Ukraine, particularly following a meeting between Zelenskyy and President Trump. Secretary of State Marco Rubio expressed frustration with claims that the Trump administration was placating Putin, highlighting the complexities and tensions surrounding international support for Ukraine.
