A Democratic U.S. congressman on Wednesday called for an emergency hearing into claims of fraud in a North Carolina election where the state is probing alleged improper handling of ballots by political operatives.

Almost a month after Republican Mark Harris declared victory in his North Carolina race for the U.S. House of Representatives, the state's election board is declining to certify the result as it probes mail-in ballots from two rural counties that have been called into question.

Democratic U.S. Rep. Gerry Connolly of Virginia on Wednesday called for an emergency congressional hearing into the matter, accusing national Republicans including President Donald Trump of hypocrisy for ignoring the case after years of claiming voter fraud without evidence.
