Georgia Senate: Biden and Trump rally voters on eve of poll
In duelling rallies, President Donald Trump and President-elect Joe Biden have urged voters in Georgia to turn out for elections on Tuesday that will decide which party controls the Senate.
Mr Trump, a Republican, and Mr Biden, a Democrat, said the votes for two Senate seats would shape the US for years.
More than three million Georgians have already cast ballots - nearly 40% of the state's registered voters.
If the Democrats win, they will control all of Congress and the White House.
Voting begins at 07:00 (12:00 GMT) and ends about 12 hours later.
The vote will decide the balance of power in the US Senate.
Republicans are currently in control, holding 52 of the 100 seats. If both Democrats win on Tuesday, the Senate will be evenly split, allowing incoming Democratic vice-president Kamala Harris the tie-breaking vote.
This would be crucial for pushing through Mr Biden's progressive agenda, including key issues such as health care and environmental regulations - issues with strong Republican opposition.
The Senate also has the power to approve or reject Mr Biden's nominees for cabinet and judicial posts.
