A key figure in Robert F. Kennedy Jr’s effort to make the ballot in all 50 states was arrested Saturday in New York City for allegedly striking a woman, according to the New York City Police Department.

Trent Pool, 37, whose petitioning company Accelevate 2020 received more than $300,000 from the Kennedy campaign in March, according to federal finance records, “wrapped his hand around [the woman’s] neck making it hard for her to breath and then struck her with a closed fist, causing pain,” the 25-year-old woman, who refused medical attention on scene, told police, according to an NYPD spokesperson.

Pool was charged with Criminal Obstruction of Breathing and Assault.
