Ukraine's Zelenskiy arrives at US Capitol

STORY: Zelenskiy traveled to Washington after seeking to shore up international support at the United Nations, on a crosstown blitz that includes meetings with U.S. President Joe Biden and military leaders at the Pentagon and an address in the evening at the National Archives museum.

Zelenskiy will meet with leaders of the Republican-led House of Representatives and House national security committees before a private session with the full U.S. Senate.

While Biden and most congressional leaders still support aide to Ukraine, and Biden's Democrats control the Senate, Zelenskiy will face a tougher crowd than when he visited Washington nine months ago.

As Ukraine's military counteroffensive grinds on and Congress stages a bitter debate over spending ahead of a possible government shutdown, a growing chorus of Republicans have questioned the billions of dollars Washington has sent Kyiv for military, economic and humanitarian needs.
