Joe Biden plans to welcome his successor, Donald Trump, to the White House on Wednesday, after the US president pledged a peaceful and orderly transfer of power to the Republican president-elect he lost to in the presidential election four years ago.

Trump, who has never acknowledged his loss in the 2020 election, scored a historic victory on November 5 that returned him to the White House, capping nearly a decade of political activism marked by his hardline positions.

Biden will join a small club of US presidents who have returned power to a predecessor in the White House.

The Democratic president will meet with Trump at 11:00 a.m. (16:00 GMT), according to a White House statement yesterday (Saturday), as the countdown begins for the former president's return to power in January.

Trump won Arizona in the US presidential election this week, US television networks predicted yesterday (Saturday), completing the Republican sweep of all seven swing states.

After four days of counting votes in this southwestern state with a large Hispanic population, CNN and NBC projected that Trump would win 11 electoral votes.

Trump ruled out yesterday (Saturday) the possibility of asking his former Secretary of State Mike Pompeo and the US Ambassador to the United Nations during his term, Nikki Haley, to be part of the administration that he is scheduled to form after being elected president for a second term.

“I will not be inviting former Ambassador Nikki Haley or former Secretary of State Mike Pompeo to join the Trump administration being formed,” the president-elect wrote on his social network, Truth Social.

“I have loved and appreciated working with them in the past, and I want to thank them for their service to our country,” the Republican billionaire added, attaching his message with his slogan “Make America Great Again.”

Democratic leader Nancy Pelosi told the New York Times on Saturday that “if the president had dropped out sooner, there might have been other candidates” besides Harris, adding that Biden’s immediate endorsement of Harris prevented a primary. However, the former House speaker praised the “enthusiasm” Harris generated during her campaign.

The 78-year-old real estate mogul and former reality TV star won by a wider margin this time, despite a criminal conviction, two impeachment attempts by Congress while in office and being accused of fascism by a former official.

Polls showed that voters' main concern was the economy and inflation, which has risen to high levels under Biden.

Biden, who dropped out of the race in July over concerns about his age, 81, called Trump on Wednesday and congratulated him on his election victory.

Second management

Trump began selecting the people for his second administration, announcing the appointment of his campaign manager, Susie Wiles, as White House chief of staff.

Wiles is the first woman to hold the prominent position, and her position is the Republican president's first appointment in his new administration. Trump described the 67-year-old Florida native as "strong, smart, innovative, loved and respected globally," adding: "Suzy will continue to work tirelessly to Make America Great Again."

Other candidates for positions in a second Trump administration reflect the big changes they are set to make.

“I’m not going to deny vaccines to anybody,” Robert F. Kennedy Jr., a prominent figure in the anti-vaccine movement whom Trump has pledged to give a “big role” in health care, told NBC News on Wednesday.

Elon Musk, the owner of SpaceX, Tesla and Platform X, who has enthusiastically backed Trump, may have a role in the Trump administration by taking on the role of scrutinizing government waste and cutting costs.

Trump is expected to reverse many of the policies that have been associated with Biden. He also returns to the White House as a climate change denier, ready to dismantle Biden’s green policies, and give the go-ahead to drill oil wells.
