"We have the system in place to consider concerns, and President Trump is 100% within his rights to look to allegations of irregularities and weigh his legal options," McConnell noted in a Monday speech in the Senate.
"According to preliminary results, voters across the nation elected and reelected Republican senators to a degree that actually stunned prognosticators," McConnell added.
"No states have yet certified their election results. We already have at least one or two states that are already on track for a recount. And I believe the president may have legal challenges underway in at least five states," McConnell continued.
McConnell also did not acknowledge Joe Biden as US president-elect or Sen. Kamala Harris (D-CA) as vice president-elect.
Senate Minority Leader Chuck Schumer (D-NY), however, called challenging the election's outcome "dangerous," noting that "lawsuits must have basis in facts" and that "Joe Biden won this election fair and square."
On 7 November Joe Biden was forecast to win the US presidential election by the US media which said that he reached the threshold he needed of 270 Electoral College votes with a win in Pennsylvania; Donald Trump has refused to admit defeat and filed lawsuits in several states, alleging voter fraud.
“We all know why Joe Biden is rushing to falsely pose as the winner, and why his media allies are trying so hard to help him: they don’t want the truth to be exposed. The simple fact is this election is far from over," Trump said in a statement Saturday after Biden was declared president-elect.
"Joe Biden has not been certified as the winner of any states, let alone any of the highly contested states headed for mandatory recounts, or states where our campaign has valid and legitimate legal challenges that could determine the ultimate victor. In Pennsylvania, for example, our legal observers were not permitted meaningful access to watch the counting process. Legal votes decide who is president, not the news media," he added.
