What is the crowd chanting? Something Polish?
I think they have been chanting “President Trump” with polish accents. That’s the best I could make it out.
Sounded like "Antifa..." then something in Polish. I think they were Antifa protesters. Later after the laying of the wreath ( the chanting was going on during the laying of the wreath - showing disrespect- which makes me believe is was Antifa), the rest of the crowd started chanting USA !!! USA !! to drown out the protesters..
