WEST CHESTER, Pennsylvania (WPVI) -- A bomb threat prompted officials to extend voting until 10 p.m. Tuesday for two polling locations in West Chester, Chester County. The Chester County Government Services Center on Westtown Road was evacuated after that bomb threat was emailed in, authorities say.

Most of the threats appear to have occurred at precincts in the Democratic-leaning Dekalb, Fulton and Gwinnett Counties.

Georgia Secretary of State Brad Raffensperger confirmed Tuesday a bomb threat was made against a polling place, but he said it was of Russian origin and not credible. Raffensperger later clarified in a subsequent press conference that the threat affected between five and seven precincts in multiple Georgia counties.

Georgia Secretary of State Brad Raffensperger (R) blamed Russia for bomb threats against polling places, which he described as not “viable” on Nov. 5.
