The trial for a son of the late Sen. Robert F. Kennedy, accused in a maternity ward scuffle, began on Monday in Westchester County, New York.

Douglas Kennedy is charged with physical harassment and child endangerment, both misdemeanors. On Jan. 7, Kennedy allegedly tried to take his 2-day-old son from the maternity ward at Northern Westchester Hospital.

Nurses tried to stop him and two claimed he injured them. One nurse said Kennedy twisted her arm and the other said he kicked her in the pelvis. Security officers eventually stopped Kennedy from leaving the hospital.

In opening statements, according to the Associated Press, the defense argued that a nurse overreacted to Kennedy’s attempt to get some fresh air for his son. The prosecution maintains Kennedy violated hospital policy when he tried to move the child.
