The Presidential Advisory Commission on Election Integrity (PEIC or PACEI), also called the Voter Fraud Commission, was a Presidential Commission established by Donald Trump that ran from May 11, 2017 to January 3, 2018. The Trump administration said the commission would review claims of voter fraud, improper registration, and voter suppression. The establishment of the commission followed Trump's false claim that millions of illegal immigrants had voted in the 2016 presidential election, costing him the popular vote. Vice President Mike Pence was chosen as chair of the commission and Kansas Secretary of State Kris Kobach was its vice chair and day-to-day administrator.
