The GOP heads of government are nervously watching President Trump erratically handle an election he is missing out on, and urge him and his team to clearly take a concrete case about the inappropriateness of the vote or accept the will of the American public.

As they watch Trump make one unsubstantiated allegation after another, Republicans are concerned about the continuing aftermath of the unsubstantiated spate of attacks by the president on a cornerstone of U.S. democracy – especially when it comes to two months of intense fighting over two Prepare successive races in Georgia that will determine the next Senate majority.

But even top Republicans are cautious about a Mercury president who has an enormous influence on the base of their party. Many are unwilling to directly question his dubious claims and instead ask him to explain his case in more detail.

GOP sources said Friday that the idea is to give Trump and his team the opportunity to stand their case and allow the disputes to resolve in court, arguing that Trump will have no choice but to the choice to allow when the lawsuits fall flat without them having to confront him.

“It is up to the Trump administration to report certain cases of electoral irregularities,” said South Carolina Senator of Justice Lindsey Graham, the chairman of the Senate Judiciary, who also defended Trump’s unsubstantiated allegations of potential fraud. “You are now looking at the voter files” and predicting more details in the next 48 hours.

Republican leaders approach him cautiously. Some, like House minority leader Kevin McCarthy, are publicly defending his claims, while others, like Senate Majority Leader Mitch McConnell, are trying to strike a middle ground.

McConnell, a cautious but deliberate leader, has carefully crafted a public message on Trump’s allegations that respects the concerns of the president and his ardent supporters but does not support their nebulous allegations of election fraud. On Friday, McConnell refused to say anything other than his finely worded statement.

Republicans argue that it is now up to the President to provide the public with details of the allegations of widespread electoral fraud in several key states that have brought former Vice President Joe Biden to the helm of the presidency.

“I think the president should leave this discussion to his lawyers,” said Roy Blunt, chairman of the Senate, whose committee is overseeing the elections. “And when they have a case to do, there is a process in which they do it, and that process is timely.”
