Biden emphasized the importance of continued funding for Ukraine and expressed strong support from the Czech leader.

However, a dispute has arisen in Congress regarding linking Ukraine aid to funds for Israel.

Republican House Speaker Mike Johnson aims to advance wartime aid for Israel this week following Iran's attack, but the White House has stated it will block any bill without funding for Ukraine.

Biden emphasized the need for a vote on Ukraine aid and highlighted the Czech Republic's support, including securing ammunition for Kyiv as US funding dwindles.

President Biden warned that Russia's aggression in Ukraine poses a risk to Europe, the US, and the world, urging action to stop Putin.

Czech Prime Minister Fiala, a witness to Russian tanks in 1968, thanked Biden for Western support of Kyiv.

US aid to Ukraine has been delayed due to political divisions in Congress, with some lawmakers blocking aid packages.

Biden's administration has ruled out aid bills that only benefit Israel.

The White House has rejected the idea of a standalone aid package for Ukraine, as some in the House of Representatives and former President Trump have expressed skepticism about providing billions of dollars in aid.

Ukraine has expressed urgency for air defenses to protect against Russian attacks, but has grown frustrated with delays in receiving Western aid.
