Adam ‘Ad-Rock’ Horovitz of the Beastie Boys joined a protest at a New York park named after late band member Adam Yauch that was vandalized with swastikas and the words ‘Go Trump!’ Horovitz spoke to the crowd saying, ‘Spray-painting swastikas at a children’s playground is a messed up thing to do.’ Protesters gathered in the park then sang The Star Spangled Banner
