(CNN) -- Virginia election officials expressed concern Monday over reports of deceptive phone calls made to voters ahead of Tuesday's midterm elections, but were hesitant to launch an immediate investigation for fear of politicizing the vote.

James Alcorn, policy advisor for the Virginia State Board of Elections, said the board had notified the U.S. Department of Justice and the state's attorney general's office, but that neither state nor federal officials were likely to "get involved" until after the election. The immediate response to the allegations, he said, was voter education. Alcorn said the state board had received a "handful" of calls and complaints about alleged deceptive phone calls made to potential voters. Jean Jensen, secretary of the board, said it had received two notarized complaints, one from a voter in Arlington and the second from a man in North Hampton.

Neither Alcorn nor Jensen described the types of phone calls the voters received, but the campaign of Jim Webb, the Democratic candidate in the Senate race against Republican incumbent George Allen, detailed two such calls to voters in those places.
