WARSAW, Poland (AP) — Poland's government is criticizing a claim by a U.S. congressman that a new Polish law glorifies Nazi collaborators and denies the Holocaust.

Andrzej Pawluszek, an adviser to Polish Prime Minister Mateusz Morawiecki, said Thursday the statement by Ro Khanna, Democrat from California was "irresponsible and shocking."

On Wednesday Khanna tweeted: "Our government should be concerned with the resurgence of anti-Semitism in Ukraine and Poland. Both countries recently passed laws glorifying Nazi collaborators and denying the Holocaust."

Khanna was referring to a new Polish law that criminalizes blaming Poland for the Holocaust crimes of Nazi Germany. The law has sparked widespread criticism, particularly in Israel, where some fear its aim is to quash discussions about wartime Polish anti-Semitic violence. However, it does not glorify Nazism or deny that the Holocaust happened.
