In this Oct. 22, 2016, photo, Republican presidential candidate Donald Trump delivers a speech during a campaign event in Gettysburg, Pa. Trump has warned for weeks of a “rigged” election, telling his supports to watch out for large-scale voter fraud, despite a lack of evidence that it exists. In the past few days, Trump has specifically raised concerns about people fraudulently voting using the names of dead people and cited research showing 1.8 million deceased people are still listed on state voter rolls.(AP Photo/ Evan Vucci)
