Roy Moore has not called Doug Jones to congratulate him on his apparent win or concede the race, a senior Jones campaign official confirms to NBC News.

Moore insisted Tuesday night that the race is too close to call and told supporters they are investigating the process for a recount.

With 99 percent of the vote in, Jones was leading 50-48 percent, or 673,236 votes to 652,300 votes — a margin of more than 20,000. The current margin appears too great for an automatic recount, which is triggered if the candidates are separated by less than half a percentage point, but Moore could call for a recount if he's willing to pay for one himself.

Alabama Secretary of State John Merrill told CNN that it is “highly unlikely” the outcome of the race will change.

"There's not a whole lot of errors that occur," he said.

Meanwhile, the Alabama GOP released a statement acknowledging Jones' apparent win, saying that “while we are deeply disappointed...we respect the voting process given to us by our Founding Fathers."
