President-elect of the United States, Joe Biden has said President Donald Trump’s refusal to concede defeat in in the country’s presidential election is “an embarrassment”.

Joe Biden has vowed to move forward with the transition despite Trump’s lawsuits, Republican obstruction and attempts to mount a blockade to the mechanisms of the presidential succession.

The General Services Administration run by a Trump appointee has yet to recognize Biden as the president-elect. Until the decision is made, Biden’s staff cannot meet with their counterparts in the White House and other federal agencies, begin background checks for potential appointees or receive security briefings. However, Biden said: “We don’t see anything slowing us down, quite frankly. The Republican resistance does not change the dynamic at all in what we’re able to do.”

Additional intelligence briefings “would be useful,” Biden added, but he maintained he could not see  anything slowing him down.

From his Twitter account on Tuesday, Trump again raised unsupported claims of “massive ballot-counting abuse” and predicted he would ultimately win the race he has already lost.

His allies on Capitol Hill, led by Senate Majority Leader Mitch McConnell, have continued to encourage Trump’s allegations.
