Biden holds press conference with Ukrainian President Volodymyr Zelensky: Watch live

Ukrainian President Volodymyr Zelensky and President Joe Biden are slated to participate in a press conference Tuesday afternoon as Zelensky visits Washington, D.C. in a last-ditch effort to salvage Ukraine aid talks ahead of the winter holiday recess.

He faces an uphill climb. GOP senators said Monday any breakthrough this week appeared unlikely, effectively punting the talks to January, as The Hill reported.

During a meeting with senators, Majority Leader Chuck Schumer (D-N.Y.) said Zelensky “made clear, and we all made clear, that if we lose, Putin wins, and this will be very, very dangerous for the United States.”

House Speaker Mike Johnson (R-La.), after meeting with Zelensky later in the morning, reiterated that any aid for Kyiv must be coupled with border security.

President Biden has requested about $60 billion in additional Ukraine support as part of a more than $100 billion supplemental spending package that has hit multiple hurdles in Congress. 

The press conference is scheduled for 4:15 p.m. EST.
