A supporter of the Republican candidate in Arizona's undecided 2nd Congressional District race has asked a court to block tallying of results from 130 ballots in Cochise County.
Republican challenger Martha McSally and Democratic incumbent Ron Barber are neck in neck in results so far.
The suit filed Tuesday in Cochise County Superior Court in Bisbee contends that election officials mishandled three precincts' provisional ballots by not sealing them in envelopes.
The suit says counting of the 130 provisional ballots should be blocked to avoid contaminating election results.
The lawyers who sued on behalf of voter William Odle did not immediately return calls for comment.
Barber's campaign is opposing the suit's request for a temporary restraining order, calling it an attempt to disenfranchise voters.
