President-elect Joe Biden and his team are not showing any concern about the breakaway group of GOP senators planning to object to the results of the Electoral College on Jan. 6.

"This stunt won't change the fact that President-elect Biden will be sworn in on January 20th, and these baseless claims have already been examined and dismissed by Trump's own Attorney General, dozens of courts, and election officials from both parties," Biden spokesperson Mike Gwin said in a statement.

The group of senators -- close allies of President Donald Trump such as Josh Hawley, Ted Cruz, James Lankford, Martha Blackburn and others -- said they will object to the slate of electors in "disputed states" unless a 10-day audit is conducted of those states' results. Yet, dozens of lawsuits about the election results have already been rejected by both conservative and liberal judges.

"Once completed, individual states would evaluate the Commission’s findings and could convene a special legislative session to certify a change in their vote, if needed," Cruz and 10 other senators and senators-elect wrote in a statement Saturday. Hawley made his intentions clear earlier this week.

That audit appears unlikely and a rejection of the slate of electors would require a majority vote in both the Senate and House. The House lies solidly in Democratic control.

Former presidential candidate Sen. Mitt Romney, R-Utah, is calling out fellow GOP senators, like Ted Cruz and Josh Hawley, who he says are undertaking an "egregious ploy" to overturn the results of the Electoral College.

Romney, himself familiar with conceding an election, joins Pennsylvania Republican Sen. Pat Toomey, who also came out against the effort Saturday.

President Donald Trump's allies, such as Hawley and Cruz, have said they plan to object to a certification of the results in a session on Jan. 6. The certification is usually a formality, but 11 senators and senators-elect plan to object this year. The move would be done in order to choose a different set of electors -- Republican electors -- even if Trump lost the vote to President-elect Joe Biden.

"The egregious ploy to reject electors may enhance the political ambition of some, but dangerously threatens our Democratic Republic," Romney said in a statement Saturday night. "The congressional power to reject electors is reserved for the most extreme and unusual circumstances. These are far from it. More Americans participated in this election than ever before, and they made their choice."

The alternate slate of electors can only be approved by a majority vote in both the Senate and House of Representatives. With the House controlled by Democrats, the move by Republicans in the Senate would largely be symbolic. Several GOP members of the House will also likely object.

Trump has made baseless claims of conspiracy and fraud daily in the two months since the election. Hawley and Cruz have made similar claims in their statements about supporting the call for different electors -- a point assailed by Romney.

"President Trump’s lawyers made their case before scores of courts; in every instance, they failed," he said in the statement. "The Justice Department found no evidence of irregularity sufficient to overturn the election. The Presidential Voter Fraud Commission disbanded without finding such evidence."

Protesters, including far-right groups like the Proud Boys, are also expected to show up in Washington on Wednesday to protest the certification of results.

"Adding to this ill-conceived endeavor by some in Congress is the President’s call for his supporters to come to the Capitol on the day when this matter is to be debated and decided," Romney said. "This has the predictable potential to lead to disruption, and worse."

"I could never have imagined seeing these things in the greatest democracy in the world," he continued. "Has ambition so eclipsed principle?"

Sen. Pat Toomey, R-Pa., has released a stinging statement defending his state’s vote for Biden -- and essentially accusing GOP objectors of trying to undermine democracy and “disenfranchise millions.”

"Allegations of fraud by a losing campaign cannot justify overturning an election. They fail to acknowledge that these allegations have been adjudicated in courtrooms across America and were found to be unsupported by evidence," the statement reads.

“A fundamental, defining feature of a democratic republic is the right of the people to elect their own leaders. The effort by Senators Hawley, Cruz, and others to overturn the results of the 2020 presidential election in swing states like Pennsylvania directly undermines this right," the statement continues.

It is rare for Republicans to feud publicly, but that is what's happening in light of Trump’s insistence that the 2020 election be overturned. Toomey's statement, which comes on the heels of another from Lisa Murkowski, R-Alaska, supporting the certification of a Biden victory, follows a statement earlier in the day by 11 senators and senators-elect saying they would join Sen. Josh Hawley, R-Mo., in objecting to the certification of election results.

“I voted for President Trump and endorsed him for re-election," Toomey concludes. "But, on Wednesday, I intend to vigorously defend our form of government by opposing this effort to disenfranchise millions of voters in my state and others.”

Sen. Lisa Murkowski, R-Alaska, put out a statement saying she will uphold the Electoral College vote on Wednesday when a joint session of Congress meets, imploring other members to join her.

“I swore an oath to support and defend the Constitution of the United States and that is what I will do January 6—just as I strive to do every day as I serve the people of Alaska," the statement reads. "I will vote to affirm the 2020 presidential election. The courts and state legislatures have all honored their duty to hear legal allegations and have found nothing to warrant overturning the results. I urge my colleagues from both parties to recognize this and to join me in maintaining confidence in the Electoral College and our elections so that we ensure we have the continued trust of the American people.”

Her statement came on the heels of a statement from 11 senators and senators-elect saying they would join Sen. Josh Hawley, R-Mo., in objecting.

Federal law requires the states to deliver certified Electoral College results to the vice president, serving as president of the Senate, and other parties by Dec. 23. Then, on Jan. 6, a joint meeting of Congress is held to certify the electoral votes and officially declare the winner of the presidential election.

In the 2020 presidential election, Biden received 306 votes and Trump received 232 votes from the Electoral College, with 270 votes needed to declare a winner.
