Legislation that would require local election officials to investigate the list of registered voters in localities has been vetoed.

Governor Terry McAuliffe vetoed the bill on Friday saying it lacked a clear standard for when and how such an investigation would be undertaken.

"By requiring 133 individual general registrars to conduct an investigation of voters under undefined standards, this bill raises serious constitutional questions," said McAuliffe in a statement. "It could expose eligible and properly registered Virginians to the risk of improper disenfranchisement."

The bill would have required investigation of the list of registered voters if it exceeded the population of persons 18 years of age or older.

McAuliffe also said the bill would have increased the administrative burden on local election officials.

Senate Bill 1105 was introduced for Senator Mark Obenshain, a Republican in the Shenandoah Valley.

Here is McAuliffe's full statement on why he vetoed the bill:
