PILF released a report last year that found more than 1,000 illegal aliens on voter rolls in just eight Virginia jurisdictions that responded to records requests from the group. Twenty percent of the more than 1,000 individuals voted, according to the group.

This report led to a bill that would have required investigations of jurisdictions whose voter rolls contain more registered than eligible voters. Virginia's Democratic Gov. Terry McAuliffe vetoed that bill.

"It's bad enough that more than a thousand people were removed from the rolls over concerns they did not meet citizenship requirements after the fact," PILF's communications director, Logan Churchwell, told the Free Beacon. "None of these were referred to prosecutors, either."
