Days after losing, Trump's advisors are increasingly convinced that their efforts to overturn Biden's election will fail, report says

• Advisors have privately acknowledged that President Donald Trump's prospects of winning a series of lawsuits and overturning the US election result are slim, The Washington Post reported Tuesday night.
• Trump has refused to concede to President-elect Joe Biden and has leveled baseless allegations of widespread fraud.
• The Trump campaign has launched lawsuits in several swing states in a bid to overturn the election result, while Biden has called Trump's refusal to admit defeat an "embarrassment."

Top advisors to President Donald Trump have privately acknowledged the president's chances of successfully disputing the result of the US presidential election are slim, The Washington Post reported Tuesday night.

Trump has refused to concede defeat to Biden, whose victory was projected by most major news networks Saturday, and has continued to claim the election was stolen from him while offering no convincing evidence to substantiate his accusations of widespread ballot fraud.

Insider and Decision Desk HQ projected on Friday that Biden would win the election.

The Trump campaign has launched lawsuits in several states claiming widespread fraud tainted the election result.

But sources told The Washington Post several of the president's aides who had most forcefully pushed his voter-fraud claims were privately skeptical of the lawsuits' chances of success. They include the White House chief of staff, Mark Meadows; the Republican National Committee's chairwoman, Ronna McDaniel; and the informal advisor Corey Lewandowski.

According to The Post, they said they were "concerned about the lawsuits' chances for success unless more evidence surfaces."

In the swing states at the center of Trump's legal campaign, both Democratic and Republican officials have said they have seen no significant evidence of voter fraud, The New York Times reported Tuesday.

A split has emerged in the GOP between those who have acknowledged Biden's win, including former President George W. Bush and Sen. Mitt Romney, and Trump loyalists who have backed his lawsuits, including Senate Majority Leader Mitch McConnell.

At a press conference Tuesday, Biden described Trump's refusal to admit defeat as an "embarrassment."

Regardless of Trump's view of the election's outcome, and unless evidence of vast voter fraud emerges, Biden will assume Trump's presidential powers at midday on January 20.
