His campaign has now established a "Election Defense Fund" to raise funds to fight the expensive legal battle in US courts that might end up in the US Supreme Court.

"I am deeply proud and excited to call Kamala Harris our next Vice President, the first woman, first South Asian American and first Black woman to ever be elected to the position," Indian-American Congresswoman Pramila Jayapal said.

"A Biden administration will be mostly positive for India," said Rick Rossow from the Centre for Strategic and International Studies think tank. "I expect most positive areas of cooperation -- notably defence -- to be maintained," he said.

India, being the world's largest democracy, is likely to play an important role in such a summit. Biden defeated incumbent President Donald Trump in the bitterly-fought presidential election that attracted a record number of Americans to cast their votes.

US President-elect Joe Biden plans to increase the number of high-skilled visas, including H-1B, and eliminate the limit on employment-based visas by country, both of which are expected to benefit tens of thousands of Indian professionals impacted by some immigration policies of the outgoing Trump administration.

US President-elect Joe Biden will work towards providing a roadmap to American citizenship for nearly 11 million undocumented immigrants, including over 500,000 from India, and will also establish a minimum admission number of 95,000 refugees annually.

Murthy, 43, who originally hails from Karnataka, was appointed America's 19th Surgeon General by then president Barack Obama in 2014.

In the first address as United States Vice President-elect, Kamala Harris thanked people of the United States "for turning out in record number" and said Americans have ushered in a "new day" for the country.

Trump has repeatedly attempted to question the validity of vote counts in key swing states and made unfounded claims that the election is being "stolen" from him.

The 77-year-old former US vice president will become the 46th president of the United States, CNN reported, after a victory in Pennsylvania, the state where he was born put him over the 270 electoral votes needed to win.

Major American media outlets started calling Biden the winner after it became clear that he has taken a major lead against Republican incumbent Donald Trump in the battleground State of Pennsylvania, which has 20 electoral college votes, making him cross the benchmark of the 270 electoral college votes.

Twitter immediately flagged Trump's tweet saying that "official sources may not have called the race when this was tweeted.

'We may be opponents - but we are not enemies. We are America'

The Trump campaign has alleged that a significant number of mail-in ballots arrived after the 8 pm deadline of closing of polls on November 3.

Biden also announced that he will introduce his plans to contain the COVID-19 pandemic on his first day in office.

As per the latest projections, Biden has 253 electoral college votes and Trump trails behind with 213. But some US media outlets have given 264 votes to Biden and 214 to Trump.

Trump has challenged the authenticity of the elections, alleging massive voters fraud and electoral malpractice. In another tweet, he said his leads in all of these states were significant on election night but suddenly started vanishing. He asserted that the lead would come back once the legal proceedings move forward.

'We believe the American people deserve to have full transparency into all vote counting and election certification, and that this is no longer about any single election. 'This is about the integrity of our entire election process,' Trump said in a statement issued by his campaign on Friday.

Even as the election was yet to be called in Pennsylvania and Georgia where Biden has taken over Trump in terms of the vote count, albeit by a thin margin, the window for Trump was fast closing down.

Biden -- who bagged 253 seats as against Trump's 213 -- appeared to be nearing the magical figure of 270 of the 538 electoral college votes.
