Republican presidential nominee Donald Trump on Monday cited studies he said showed rampant voter fraud, saying the Nov. 8 election was "rigged" against him even as Republican lawyers called his allegations unfounded.
Trump, a New York businessman making his first run for public office, has sought to raise fears of a flawed election as he has fallen in opinion polls against Democrat Hillary Clinton.
"They even want to try to rig the election at the polling place," Trump told a rally in Green Bay, Wisconsin. "So many cities are corrupt and voter fraud is very, very common."
