James W. Trainor, 36, was arrested for allegedly throwing a brick through the front window of Sen. Mark Warner’s (D-VA) regional office early Monday morning, according to Politico. Trainor is being charged with felony property damage after he allegedly threw the brick at around 7:30 a.m. ET. “We think this is kind of a random, isolated incident. Not to say the act is random—we do believe Trainor meant to do this,” Roanoke City Police spokeswoman Caitlyn Cline said. “But we don’t think it’s a precursor to anything bigger at this point.” CNN reports that law enforcement was first called to the area after someone saw the individual “walking around...carrying bricks.” Rachel Cohen, Warner’s communications director, said that no one was at the office at the time of the attack.
