Poland's civil liberties index score was 49 out of 60 in 2020. The current president of Poland has cracked down on the free press. Reporters Without Borders reported that "the public service broadcaster in 97 percent of cases, portrayed President Duda in a positive light, while the opposition candidate in 87 percent of cases was portrayed in a negative light."

Vice President Harris, of course, blames Belarus for the ongoing migrant crisis at Poland's border.

In October of 2021, The Associated Press reported that "Poland's lawmakers approved the speedy construction of a $402 million barrier wall on the European Union member's border with Belarus to stop the increasing flow of migrants."
