US media outlets say the Democratic Party has won at least one of two Senate runoff elections in the state of Georgia, with the other race still too close to call.
Attention is focused on the outcome, which will determine whether President-elect Joe Biden's Democratic Party will control both chambers of Congress when he takes office on January 20.
Voting took place for two of the 100 Senate seats on Tuesday. The Republican Party had 50 seats after the November elections, and the Democratic Party had 48.
Vote counting is still under way, but ABC television and other media project that Democratic newcomer Raphael Warnock has defeated Republican incumbent Kelly Loeffler. The victory gives the Democrats 49 seats.
The other runoff is also a race between a Republican incumbent and a Democratic newcomer.
ABC television says the count is neck to neck at 50 percent each, with 98 percent of the expected vote reporting.
If the Democrats win, they would have the same number of seats as the Republicans, meaning an effective Senate majority since Vice President-elect Kamala Harris will serve as the chamber's president.
