"In the Marines, I learned what it means to fight for our democracy," tweeted Democrat Dan McCready, who lost to Harris by 905 votes. "I never imagined I would watch our democracy come under attack right here at home," McCready added.
It's not clear if the U.S. House of Representatives will also investigate the possible fraud in the Ninth District race, which possibly involved ballot fraud and discarded ballots.
The North Carolina board could still order a new election, which may involve a new primary as well, as some Republicans would like to get Harris out of the race for the seat in Congress, worried that he will be too tainted by the charges of election fraud.
The decision to extend the investigation of any election fraud into 2019 means that the U.S. House will start the 116th Congress with Democrats holding a 235-199 edge in the House - with the one vacancy from North Carolina.
