Mitch McConnell's speech follows a groundswell of leading Republicans who now say that Biden is the winner of the presidential election, essentially abandoning Trump's assault on the outcome after the Electoral College confirmed Biden's victory.

One day after the Electoral College affirmed Joe Biden as US president-elect, the top Republican in Congress broke weeks of election silence and sent a sober message to a defiant President Donald Trump: it's over.

The Senate Majority Leader Mitch McConnell was among many congressional Republicans who had refused to acknowledge Biden's defeat of President Donald Trump, who has continued to make claims of election fraud and refused to concede.

But as Trump's unprecedented bid to overturn the results crashed and burned, and with electors on Monday confirming Biden's victory 306 to 232, McConnell became the most powerful member of the Republican Party to publicly acknowledge Biden's victory.

"The Electoral College has spoken. So today I want to congratulate President-elect Joe Biden," McConnell said on the Senate floor.

"Many of us hoped that the presidential election would yield a different result, but our system of government has processes to determine who will be sworn in on January 20," he added. McConnell also called Biden someone “who has devoted himself to public service for many years.” 

He also congratulated Vice President-elect Kamala Harris, saying “all Americans can take pride that our nation has a female vice president-elect for the very first time.”

Meanwhile Biden told reporters that he called McConnell on Tuesday to thank him for the remarks. As Biden departed Wilmington, Del., to campaign for Democrats in the Georgia runoff elections for Senate, he said they had a “good conversation.”

"We agreed to get together sooner than later,” Biden said.

The Senate leader's speech followed a groundswell of leading Republicans who have now said that Biden is the winner of the presidential election, essentially abandoning Trump's assault on the outcome after the Electoral College on Monday confirmed Biden's victory.

While some Republican lawmakers signaled they would not give up the fight, others like retiring Senator Lamar Alexander directly urged Trump to "put the country first" and help Biden as he transitions to the White House.

Joining the chorus, Russian President Vladimir Putin on Tuesday congratulated Biden on his victory and said he was "ready for collaboration" on issues like global security.

Biden, 78, is expected to take a tougher stand against Russia, in comparison to Trump, whom the Democrat slammed during the campaign for having "embraced so many autocrats around the world, starting with Vladimir Putin."

Biden is riding high after members of the Electoral College gathered in all 50 states and the capital Washington to put the official stamp on the will of the people. 

The vote offered no surprises – and in more traditional times the rather arcane Electoral College process would be just a formality in the normal transfer of power.

But Trump, in unprecedented fashion, has yet to acknowledge his own defeat in the chaotic election that will see him exit the White House after a single four-year term.

In welcoming the vote, Biden delivered a speech saying US democracy proved "resilient" against Trump's "abuse of power."

"It's time to turn the page," Biden told the bitterly divided country.

He also issued his first extended attack on Trump since the election, saying the president and his allies "refused to respect the will of the people, refused to respect the rule of law, and refused to honor our constitution."

Biden praised voters for casting ballots in record numbers on November 3 despite fears of Covid-19 and "enormous political pressure, verbal abuse and even threats of physical violence" against those running the election.

Political Battleground Georgia 

Even as the door essentially shut on unprecedented efforts to overturn the results, Trump remained defiant, insisting in a series of tweets that he won a "landslide victory" and that there were still "tremendous problems" with the vote.

In a threatening move against Republican leaders in Georgia, where he has made baseless claims of massive voter fraud, he retweeted a pro-Trump lawyer who posted a picture of Georgia's governor and secretary of state, saying "they will soon be going to jail."

Biden campaigns later Tuesday in Georgia, where Democratic Senate candidates are locked in tight runoffs whose results will determine the balance of power in the Senate, and thus shape Biden's presidency.

Democrats need to flip both seats in order to seize Senate control, while Republicans must hold just one to maintain their majority.

Republicans have framed Georgia as must-win races, with the state forming the last line of defense against what they describe as a radical, left wing agenda.

"Georgia is the firewall to socialism," one of the Republican incumbents, Senator Kelly Loeffler, said Monday. "We have to hold the line here."

Meanwhile Trump announced Monday that Attorney General Bill Barr, who contradicted his fraud claims, would leave his post next week.
