U.S. Sen. Kevin Cramer's son, Ian Cramer, has been charged with manslaughter after a crash that killed a North Dakota sheriff's deputy. Court documents allege that Ian was traveling over 100 mph and had two flat tires when he slammed head-on into Deputy Paul Martin's squad car. Ian is facing multiple felony counts and his attorney has not yet responded to a request for comment. Sen. Cramer has stated that his son suffers from "serious mental disorders which have been compounded by substance abuse."
