Washington (Aletihad)

Joe Biden will meet with President-elect Donald Trump at the White House on Wednesday after the US leader pledged an orderly transfer of power following the Republican's decisive election victory.

Biden and Trump will meet at the Oval Office at 11:00am (1600 GMT), the White House said on Saturday, with the clock ticking down to the ex-president's return to power in January.

Trump sealed a historic comeback to the White House in the November 5 election after defeating Harris earlier this week. The 78-year-old won wider margins than before.

Exit polls showed that voters' top concern remained the economy and inflation that spiked under Biden in the wake of the Covid pandemic.

Biden, who dropped out of the race in July over concerns about his ability to continue at the age of 81, called Trump to congratulate him after his election win.

Trump is set to be sworn in for his second term as president on January 20.

Trump's team

Trump has begun to assemble his second administration, naming campaign manager Susie Wiles to serve as his White House chief of staff.

She is the first woman to be named to the high-profile role and the Republican's first appointment to his incoming administration.

"Susie is tough, smart, innovative, and is universally admired and respected," Trump said of the steely 67-year-old Florida native.

"Susie will continue to work tirelessly to Make America Great Again."

The other frontrunners for a place in the Trump 2.0 administration reflect the significant changes it is likely to implement.

Robert F. Kennedy Jr., a leading figure in the anti-vaccine movement for whom Trump has pledged a "big role" in health care, told NBC News on Wednesday that "I'm not going to take away anybody's vaccines."

The world's richest man, Elon Musk, could also be in line for a job auditing government waste after the SpaceX, Tesla and X boss enthusiastically backed Trump.

Trump is expected to wield the axe on many of Biden's signature policies.
