What can we expect from Zelensky and Biden's meeting?published at 18:28 Greenwich Mean Time 21 December 2022
This may be Zelensky's first foreign trip since the war in Ukraine began, but it's not his first time visiting Washington or meeting President Biden.
The pair last met in person at the White House in September 2021. That meeting was their first. It was also the first time a Ukrainian leader had visited the White House in more than four years.
Today, they'll be meeting after dozens of phone and Zoom calls held over months of war - and the main topic of conversation will be continued support for Ukraine by the US.
With the announcement today of another $1.85bn (£1.5bn) worth of military aid, it's thought they will discuss weaponry, what that latest package offers and - on Zelensky's part - whether there's more to give.
After the meeting, which will take place in the Oval Office between 14:30 and 16:30 local time (19:30 and 21:30 GMT), the two leaders will hold a press conference.
