The Polish Foreign Ministry summoned the U.S. ambassador on Thursday about the actions of a television station, it said in a statement without naming the station or specifying what it believes it did wrong.
Poland has previously been at odds with the United States over Discovery-owned news channel TVN24, which is critical of the government.
TVN24 recently contributed to stirring a heated debate in Poland by airing a documentary alleging late John Paul II knew about sexual abuses by Catholic clergy before becoming pope.
