Donald Trump is putting out a call for election observers to prevent against voter fraud at the polls.

“Help Me Stop Crooked Hillary From Rigging This Election!,” the campaign says in bold on the Election Observer volunteer signup page.

Trump has been concerned for a long time about the possibility that the vote count in various precincts could be unfairly manipulated on Election Day.

Trump’s concern stems from Border Patrol’s assertion that illegal immigrants are gaining access to the United States purely to vote in November’s election, and in fact are being hurried up in order to collect more votes.
