Two U.S. senators wrote President Andrzej Duda of Poland to express their concern about a rise in what they said was antisemitic discourse, citing one of his own statements. The letter sent Tuesday by Sen. Jacky Rosen, D-Nev., and James Lankford, R-Okla., on several occasions notes the close defense ties of the United States and Poland and suggests a failure to address the antisemitism, and to advance Holocaust restitution, could impede the growth of the relationship.
