Jill Stein calls for investigation of voting system

Former Green Party nominee Jill Stein is calling for an investigation of the nation's voting system and voting machines.

Stein wants the Department of Justice to look into the election system, saying that her recount and recount attempts in Michigan, Pennsylvania and Wisconsin uncovered "major problems."

In her letter to the Attorney General, Loretta Lynch, Stein lists concerns over voting machine vulnerability, human error, machine error, and tampering.

Lynch has not yet responded to the request.
