Polish President Andrzej Duda is expected to meet with Republican presidential candidate Donald Trump on Sunday in Pennsylvania, a critical battleground state for the upcoming November 5 election. This potential meeting, which would mark a rare instance of a foreign leader accompanying a U.S. candidate on the campaign trail, is still unconfirmed as Trump has yet to respond to the invitation. Duda is known for his strong ties with Trump from their time in office together (2017-2021) and is expected to discuss significant issues including Polish-U.S. relations, Poland's security, and the war in Ukraine. Their visit will take place at the National Shrine of Our Lady of Czestochowa, which has historical importance and was previously visited by Pope John Paul II. This appearance comes as world leaders gather for the UN General Assembly, with Duda also set to attend that event in New York City next week. Both the Trump campaign and the Polish embassy have not provided comments on the meeting as of now.
