NORFOLK, Va. (WVEC) -- Widespread voter fraud. That's the claim from Donald Trump.

Without offering any evidence, Trump alleged "millions of people" voted illegally for Hillary Clinton. He went on, in a Tweet, to specifically name Virginia, New Hampshire and California as the places where it supposedly happened.

The Virginia Board of Elections, writing in an e-mailed statement said: "The claims of voter fraud in Virginia during the November 8 election are unfounded. Virginia's election was well administered by our 133 professional local registrars, with help from hundreds of election officials and volunteers who worked to guarantee a good experience for eligible Virginia voters. The election was fair and all votes cast by eligible voters were accurately counted."

Virginia Governor Terry McAuliffe also disputed the allegation, with his spokesman, in an e-mail to 13News Now, saying: "Obviously the Governor is concerned that anyone would make such false claims, much less the President-elect of the United States.

Christopher Newport University political science professor Quentin Kidd says there are "very, very few cases of actual voter fraud," and he suggests that Trump should choose his words more carefully.

"Donald Trump is no longer candidate-for-president Donald Trump," he said. "He's President-elect Donald Trump. And President-elect Donald Trump needs to be more thoughtful and considerate in his words, especially when they call into question the way in which we select our leaders and the process and integrity of that process. It's a serious thing."

Old Dominion University political science professor Jesse Richman says Virginia's election "was largely well conducted," even if it's eventually proved that a small number of non-citizens did manage to cast ballots.

"There's no way with Virginia, as with the national vote, you're looking at margins that are far too big to be at all plausibly shaped by the low levels of illegal voting that do occur," he said. "We don't have evidence of major fraud."

13News Now spoke directly with the voter registrars offices in Virginia Beach and Chesapeake. They said they have no knowledge of any voter fraud. The T.V. station is still waiting to hear back from the registrars in Norfolk, Portsmouth and Hampton.
