WASHINGTON (CNN) - At least three cases of possible voter suppression at election sites around Virginia will be investigated by state police, according to Virginia election officials.
The cases were reported in the city of Richmond, Fairfax County and Fauquier County, according to Nancy Rodrigues, Virginia's executive secretary of the Board of Elections.
In once case she said the "over presentation of law enforcement" at one polling location was called in. In another case someone was playing a recording of right-wing radio host Rush Limbaugh loud enough to violate the no campaigning within 300 feet of a voting location.
"We are working very closely with local and state police to investigate these allegations," Rodrigues said during a press conference in Richmond Tuesday.
A spokesperson for the election board said they could not say what the third incident was and could not comment further on the cases, only saying that investigations are underway on all three incidents.
