Donald Trump’s administration on Monday finally cleared the way for President-elect Joe Biden to transition to the White House, giving him access to briefings and funding even as Trump vowed to continue fighting the election results.

Trump, a Republican, has continued to alleged widespread voter fraud in the November 3 election without providing evidence.

Reuters reported that although Trump did not concede or acknowledge his Democratic rival’s victory on Monday, Trump’s announcement that his staff would cooperate with Biden’s represented a significant shift and was the closest he has come to admitting defeat.

Biden won 306 state-by-state electoral votes, well over the 270 needed for victory, to Trump’s 232.

This comes after Trump’s legal efforts to overturn the election have almost entirely failed in key battleground states, and a growing number of Republican leaders, business executives and national security experts have urged the president to let the transition begin.

Reuters reported that critics have accused the president of undermining US democracy and undercutting the next administration’s ability to fight the coronavirus pandemic with his refusal to accept the results.

On Monday, the General Services Administration, the federal agency that must sign off on presidential transitions, told Biden he could formally begin the hand-over process. GSA Administrator Emily Murphy said in a letter that Biden would get access to resources that had been denied to him because of the legal challenges seeking to overturn his win.

That means Biden’s team will now have federal funds and an official office to conduct his transition until he takes office on January 20. It also paves the way for Biden and Vice President-elect Kamala Harris to receive regular national security briefings that Trump also gets, Reuters reported.
