The US state of Arizona has elected its first female senator, after Democrat Kyrsten Sinema beat Republican Martha McSally in a tight race.
Ms Sinema is the southern state’s first Democratic senator since 1994.
The win narrows the Republican majority to four seats (51-47), with two more Senate races remaining unresolved.
In Florida, a recount has been ordered by law after unofficial results fell within a 0.5% margin. Mississippi will hold a run-off vote later this month.
With almost all the votes counted, Ms Sinema had a lead of 1.7% of her rival.
She now becomes Arizona’s first female senator.
Ms Sinema, 42, later addressed her cheering supporters in Phoenix, speaking of the urgent need to heal the bitter political rancour dividing Americans.
She paid tribute to the memory of the late John McCain, who represented Arizona in the Senate, saying he had set a shining example of how to put national interests above party political ones.
Ms McSally, a 52-year-old former combat fighter pilot, conceded defeat.
