Riley Clark, the 23-year-old daughter of U.S. Rep. Katherine Clark of Massachusetts, was arrested during a protest in downtown Boston on Saturday night and charged with assault after a police officer was injured. The Boston Police Department said she was observed defacing a monument with spray paint and a group of protesters surrounded officers while screaming profanities. Rep. Clark tweeted about her daughter's arrest, and Riley is expected to be arraigned in Boston Municipal Court.
