President Joe Biden is expected to travel to Poland this month to mark the anniversary of the Russian invasion of Ukraine, according to three people familiar with the planning.

The current planning underway is for Biden to visit Poland in late February, sources told NBC News.

The sources noted that the trip is not final until announced by the White House and that plans could change.

A spokesman for the National Security Council declined to comment.

It was not immediately clear if additional stops would be added to the trip.

NBC News was the first to report last month that Biden was considering a trip to Europe, possibly including Poland, to commemorate the first anniversary of the war that began on February 24, 2022.

Sources at the time said the White House was considering ways Biden could mark the milestone with the aim of drawing attention to Ukraine’s resistance against Russia’s brutal military campaign and reaffirming US solidarity with the Ukrainian people through as the conflict enters a new phase.

Last month, Biden said the United States would send 31 Abrams tanks to Ukraine.

The move was a setback for the Biden administration, which had resisted pressure from Germany to send them to Ukraine.
