The United States is scrutinizing developments in Poland, the U.S. trade czar said on Sunday when asked if Washington was concerned about the European Union's rule of law inquiry into Poland and Standard and Poor's cut to Warsaw's credit rating. "As a fellow democracy we do follow developments here very closely," U.S. Trade Representative Michael Froman told reporters during his visit to Google Campus in Warsaw. "We certainly do follow it. As a democracy, we want to make sure that Poland's democracy continues to address the issues."
