CCTV News:On the 10th local time, US Democratic presidential candidate Biden held a press conference, saying that his transition team had begun to prepare for the formation of a new government, and stressed that nothing could stop this. On the other hand, Republican presidential candidate and US President Trump said on social media that he would win the election and there was fraud in counting votes.

Biden said that Trump’s refusal to admit defeat made many Americans feel anxious. He thought Trump’s move was embarrassing and not good for his political legacy as president. He expressed his expectation to start a dialogue with Trump. When asked if he would take legal action to force Trump to admit defeat, Biden said he didn’t think it was necessary. However, according to CBS, Biden can’t officially start to take over the presidential power because the General Affairs Administration of the United States, which has officially opened the presidential power transfer procedure, has not officially determined the winner of the election. In this regard, an official of Biden’s campaign team who asked not to be named said that Biden would consider taking legal action to deal with the current situation.

On the other hand, Trump posted on social media twice on the 10th, saying that he would win, and there was fraud in counting votes in the general election. In an American Fox News program broadcast on the evening of 10th local time, White House Press Secretary Kelly McNarney said with a large stack of paper documents that it was 234 pages of sworn written testimony, which could prove that there was election fraud in this election. McNarney, for example, said that in wayne county, Michigan, 60% of the votes had the same signature, and 50 votes had been counted repeatedly. Bill Stepin, Trump’s campaign manager, said the day before that Trump was "not retreating" and "still fighting" and would continue to seek to initiate legal proceedings in several key States in response to the vote count results of the general election. However, according to US media reports, although the Trump campaign team is actively seeking donations to pay tens of millions of dollars in litigation fees and recount fees, some Republican donors have indicated that they are unwilling to continue to entangle in legal proceedings. These lawsuits will not change the current election outcome, and they have shifted their focus to maintaining the Republican majority status in the Senate.
