The North Carolina State Board of Elections will hold two — and possibly, three — days of hearings starting Feb. 18 on allegations that an operative tied to a Republican’s U.S. House campaign engaged in absentee ballot fraud last year.

The hearing, according to The News and Observer, was announced by the recently reworked elections board Monday. While the board only expects the hearing to last two days, it has reserved the site of the hearing for three days, the News and Observer reported.

The fraud allegations center on an absentee ballot operation run by a local operative, Leslie Dowless McCrae, who has denied wrongdoing. McCrae has been connected to the campaign of Republican Mark Harris, who unofficially won the North Carolina 6th District congressional race by 905 votes. His race has not been certified by the board due to the allegations.
