More than 500 ineligible voters in North Carolina cast ballots in the 2016 general election, according to a State Board of Elections audit released Friday.
State officials said the illegal votes did not affect the outcome of any race.
Most of the 508 voters were active felons at the time of the election and only made up a small percentage of the total 4.8 million ballots cast. Another 24 ballots were believed to have been cast by individuals who voted multiple times.
The board did not complete a similar report after the 2012 elections, which makes it impossible to know if last year's levels were an increaes.
President Trump has said on multiple occasions that illegal immigrants voted but provided no evidence for the allegations.
