'Do what needs to be done': Donald Trump finally agrees to allow Joe Biden transition to begin but won't concede

Trump acknowledges it is time for the General Services Administration to work with the president-elect's transition team

President Donald Trump came his closest yet to admitting election defeat Monday after the government agency meant to ease Joe Biden's transition into the White House said it was finally lifting its unprecedented block on assistance.

Trump acknowledged it was time for the General Services Administration to "do what needs to be done."

In the same tweet, he insisted that he was still refusing to concede, saying: "Our case STRONGLY continues, we will keep up the good fight, and I believe we will prevail!"

But for the Republican to sign off on the GSA's decision to work with the Biden transition team signalled that even he sees the writing on the wall after three weeks of evidence-free claims that the November 3 election was stolen from him.

This means that Biden's team will now have access to funds, office space and the ability to meet with federal officials.

Biden's office, which hours earlier announced a highly experienced group to be nominated for top US foreign policy and security posts, said the GSA would now allow "support necessary to carry out a smooth and peaceful transfer of power."

"In the days ahead, transition officials will begin meeting with federal officials to discuss the pandemic response, have a full accounting of our national security interests, and gain complete understanding of the Trump administration's efforts to hollow out government agencies," Biden's transition director Yohannes Abraham said in a statement.

The sudden break in Trump's dogged attempt to deny Biden's win came after Michigan became the latest state to certify its results and more powerful Trump supporters came out demanding that the impasse ends.

Earlier, Biden announced a foreign policy and national security team crammed with veterans from the Barack Obama years, teeing up an end to the upheaval under Trump and a return to traditional US diplomacy.

Top of the list was former State Department number two Antony Blinken, tapped for secretary of state.

Biden also named the first female head of intelligence, the first Latino chief of Homeland Security, the first woman as treasury secretary, and a heavyweight pointman on climate issues -- Obama-era top diplomat John Kerry.

The list put out by Biden's team ahead of a formal announcement Tuesday demonstrated a push to bring back the US role of a leader in multilateral alliances, in contrast to Trump's "America first" regime.

"They will rally the world to take on our challenges like no other -- challenges that no one nation can face alone," Biden tweeted. "It's time to restore American leadership."

Blinken, a longtime advisor to Biden, will spearhead a fast-paced dismantling of Trump's go-it-alone policies, including rejoining the Paris climate agreement and the World Health Organization and resurrecting the Obama-crafted Iran nuclear deal.

Biden named the first woman, Avril Haines, as director of national intelligence, and Cuban-born Alejandro Mayorkas to head the Department of Homeland Security, the agency whose policing of tough immigration restrictions under Trump was a frequent source of controversy.

Signalling the Democratic president-elect's campaign promise to raise the profile of global warming threats, he named Kerry as a new special envoy on climate issues.

And in a further message of US reengagement with the international community, Biden named career diplomat Linda Thomas-Greenfield for UN ambassador.

Jake Sullivan, who also advised Biden when he was vice president under Obama, was named national security advisor.

Picked to manage the world's biggest economy as Treasury secretary was Janet Yellen, who will make history as the first woman in the job if confirmed. The 74-year-old was confirmed as Federal Reserve chairwoman under Obama in 2014 and replaced by Trump four years later.

The picks underline an emphasis on professionals whom Biden already knows well, in contrast to the Trump White House where officials were often picked without having a traditional background for the job or proved incompatible and departed in acrimony.

The president, meanwhile, has largely halted at least his public work duties, while heading out to a golf course he owns in Virginia half a dozen times since the election.

He has also not taken questions from reporters since the election -- a previously unimaginable silence from a president who for most of his time in office sparred near daily with the press.

His options for overturning the election, however, are dwindling rapidly in the face of repeated court defeats.

With Biden having won a comfortable victory, Trump's last card is to disrupt the normal routine process of state-by-state certification of results, followed by the formal December 14 vote by the Electoral College. However, that too is bearing little fruit.

More cracks appeared in the facade of Republican unity on Monday when Senator Rob Portman said it was "time to expeditiously resolve any outstanding questions and move forward."

There was also a push from Trump's highest-profile Wall Street backer, Stephen Schwarzman, head of the Blackstone private equity group, who told Axios "the country should move on."
