Responding to questions from reporters on Trump not conceding the race, Biden hoped that at the end it's all going to come to fruition on January 20th.

The world is watching what's taking place here. We're going to count all the votes, Pompeo said.

Outgoing US President Donald Trump has declined to concede the closely-fought November 3 presidential race to Democrat Biden and is mounting legal fights in several key battleground states, but there has been no evidence of voter irregularities or widespread fraud in the election -- billed as one of the most divisive and bitter in recent American history.

Alleging that the order made by the Pennsylvania Supreme Court was unconstitutional, the attorney generals said the state overstepped its constitutional authority in accepting late ballots and violated the election clauses of the Constitution and that voting by mail creates voter fraud risks.

Trump's firing comes days after Esper in an interview told The Military Times that he was not a "yes man" for the president.

Trump had said that he worked on removing a large number of bureaucratic obstacles to fast-track development and approval of a vaccine.

Dr Murthy, 43, a former United States Surgeon General, along with two other co-chairs -- Dr David Kessler and Dr Marcella Nunez-Smith -- would lead a team of leading public health experts who will advise Biden and Vice President-elect Kamala Harris on the deadly virus.

The Biden team updated its website to showcase four policy areas the incoming administration will prioritise: COVID-19, economic recovery, racial equity and climate change.

Bush, however, also said that outgoing President Donald Trump has the right to request recounts and pursue legal challenges, with any unresolved issues to be "properly adjudicated".

The 56-year-old Democratic Senator from California, who on Saturday became America's first female, first Black and first South Asian vice president-elect, represents a new face of political power.

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.
