The Democratic Party of US President-elect Joe Biden is on the verge of taking control of the Senate as results come in from two elections in Georgia.
Pastor Raphael Warnock is projected to win one seat. Fellow Democrat Jon Ossoff leads narrowly in the other.
If they both win, Mr Biden will have a much better chance of pushing through his legislative agenda.
The election is being rerun because of Georgia's rule that a candidate must take 50% of the vote in order to win.
None of the candidates in November's general election met that threshold.
