It added that it "recognizes that the potential outcome of these activities is in line with the goals of a hybrid war aimed at causing divisions and tensions within Polish society."
"Therefore," the statement said, "the Polish Ministry of Foreign Affairs has invited the US ambassador to inform him about the situation and its consequences in the form of reducing Poland’s capacity to deter a potential enemy and diminishing its resilience to threats."
The US envoy, Mark Brzezinski, arrived at the Polish foreign ministry building in Warsaw on Thursday afternoon, news outlets reported.
The Polish foreign ministry did not name the station or specify what it believes the broadcaster did wrong.
Warsaw has previously been at odds with Washington over US-owned news channel TVN24, which is critical of the Polish government, the Reuters news agency reported.
It noted that TVN24 recently aired a documentary alleging that the late Polish Cardinal Karol Wojtyła knew about cases of child abuse by Catholic priests before he became Pope John Paul II. The documentary stirred a heated debate in Poland.
The US embassy in Warsaw had no immediate comment, Reuters reported.
