A curious thing happened as Fulton County, Ga., election officials counted mail-in ballots in the days after the election. In the early hours of Nov. 5, a surge of some 20,000 mail-in votes suddenly appeared for Joe Biden, while approximately 1,000 votes for President Trump mysteriously disappeared from his own totals in the critical swing state, where Biden holds a razor-thin lead.

The large disparity of gains between the two candidates "was something I had never witnessed before in my years of election monitoring,” said Favorito, a career IT professional who has been a leading advocate for election integrity in the state over the past two decades. He says he is not a Republican or Trump supporter.

"Fulton County elections officials falsely announced that the counting of ballots would stop at 10:30 p.m.,” Georgia Republican Party Chairman David Shafer. “Officials unlawfully resumed the counting of ballots after our observers left the center."

Favorito fears that what he observed on Nov. 5 was not an isolated incident. “There could have been multiple 20,000-batch irregularities,” he said, “but they never got reported because they cleared out the observers."
