WASHINGTON (AP) President Joe Biden and Ukraines leader, Volodymyr Zelenskyy, will meet at the White House on Tuesday as the U.S. administration steps up the pressure on Congress to provide billions more in aid to Kyiv in its war with Russia .

The visit is intended to underscore the United States unshakeable commitment to supporting the people of Ukraine as they defend themselves against Russias brutal invasion, the White House said in a statement Sunday. As Russia ramps up its missile and drone strikes against Ukraine, the leaders will discuss Ukraines urgent needs and the vital importance of the United States continued support at this critical moment.

Zelenskyys office confirmed that he had accepted Bidens invitation. He also has been asked to speak to a meeting of all senators.

Biden has asked Congress for a $110 billion package of wartime funding for Ukraine ($61.4 billion) and Israel, along with other national security priorities. But the request is caught up in a debate over U.S. immigration policy and border security.

Zelenskyy traveled to Buenos Aires to witness the swearing-in on Sunday of Argentinas new president, Javier Milei. The Ukrainian leader had been scheduled to address U.S. senators by video last week, but had to cancel the appearance, according to Senate Majority Leader Chuck Schumer of New York.
