Earlier on Wednesday, McDaniel's campaign held a press conference to announce that it had yet to file a formal challenge to the election results. One of the state senator's lawyers said the campaign would not file a challenge unless it had enough evidence. Yet later in the conference, another McDaniel lawyer said he expected to file within the next 10 days.
