Donald Trump will become the next US president after clinching victory in the key battleground state of Wisconsin.
With that victory in hand, Trump crossed the 270 electoral votes needed to be declared victorious in the vote that will see him return to the White House.
"America has given us an unprecedented and powerful mandate," Trump said early on Wednesday to a roaring crowd of supporters at the Palm Beach County Convention Center in Florida.
US networks Fox News, CNN and NBC declared Trump the incoming president after projecting that he had secured enough Electoral College votes following wins over Harris in battleground states including Pennsylvania and Wisconsin.
Trump is the first former president to return to power since Grover Cleveland regained the White House in the 1892 election.
He is also the first person convicted of a felony to be elected president and, at 78, is the oldest person elected to office.
Modi offers 'heartiest congratulations' to Trump
Indian Prime Minister Narendra Modi has joined world leaders in congratulating Trump.
"As you build on the successes of your previous term, I look forward to renewing our collaboration to further strengthen the India-US Comprehensive Global and Strategic Partnership," Modi said on social media.
"Together, let’s work for the betterment of our people and to promote global peace, stability and prosperity."
The two right-wing leaders enjoy warm relations, with Modi hosting Trump at a major political rally in his home state of Gujarat in 2020.
Last month, Trump praised the Indian leader in a podcast hosted by comedian Andrew Schultz, calling him "a friend of mine."
