LOUISVILLE, Ky. — A poll worker was arrested Tuesday and charged with assault and interfering with an election for allegedly choking a voter and pushing the voter out the door, an official said.

Election officials called police, and the voter wanted to file charges, said Paula McCraney, a spokeswoman for the Jefferson County Clerk.

“That about tops off the day,” McCraney said.

It wasn’t immediately clear what sparked the altercation. The name of the poll worker was not released and a Louisville police spokesman did not immediately return calls seeking comment.
