Pence was speaking during a meeting with Polish President Andrzej Duda in Warsaw, on his second day of the trip to Poland.
Around 10 million Poles live in the United States, making them one of the country’s biggest ethnic minorities.
On Sunday (September 1) Pence was among delegates from over 40 countries who came to Warsaw to commemorate 80 years since the start of World War Two in Poland.
Ireland, Iceland and Britain are next stops on Pence’s European trip.
