On Tuesday, President-elect Joe Biden said the reluctance of President Donald Trump to admit defeat in the US Presidential election was a 'embarrassment'.

Biden said, "Yeah, I just think it's an embarrassment, quite honestly, the only thing that, I think it's not going to improve the President's reputation ... I think it's going to all come to light on January 20 at the end of the day, and between now and then an optimistic belief is that the American people can recognize that a transition has taken place," reported ANI news agency.

He also said he recognized the sense of loss of the people who voted for Trump, adding that most of them wanted the nation to unite.

I think they know we have to come together. I think they're ready to unite, and I think we can bring this nation out of the bitter politics we've seen over the past 5.6.7 years, "Biden said." We're ready to unite.

In several states, including Pennsylvania, which has 20 electoral college votes, Georgia (16), Michigan (16), Nevada (six), the Trump campaign and his Republican Party have filed several lawsuits calling for the recount of votes in Wisconsin, which has 10 electoral college votes. The cases vary from municipal courts up to the Supreme Court of the United States.

The Trump campaign and the Republican Party, refuted by state authorities and the Democratic Party, have leveled allegations of serious voter fraud and electoral malpractice.
