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.

A group of GOP senators has come out with an extraordinary claim about “allegations of voter fraud” and “irregularities” that they say hasn’t been seen “in our lifetimes” -- claiming they will object on Wednesday during a joint session of Congress to count electoral votes "unless and until" a 10-day audit of election returns in disputed states is completed.

The eleven senators and senators-elect plan to object to the certification of electors in some states where votes were disputed, though no list of states was given.

Also, no widespread fraud has been found by any court to date and such claims have been refuted by secretaries of state.

The senators -- Ted Cruz, R-Texas; Ron Johnson, R-Wis.; James Lankford,  R-Okla; Steve Daines, R-Mont.; John Kennedy, R-La., Marsha Blackburn, R-Tenn., and Mike Braun, R-Ind., as well as Senators-Elect Cynthia Lummis, R-Wyo.; Roger Marshall, R-Kan.; Bill Hagerty, R-Tenn.; and Tommy Tuberville, R-Ala. -- say they expect their efforts to fail and join Sen. Josh Hawley, R-Mo., who also has announced his intention to object.

“The election of 2020, like the election of 2016, was hard fought and, in many swing states, narrowly decided.  The 2020 election, however, featured unprecedented allegations of voter fraud, violations and lax enforcement of election law, and other voting irregularities," the statement says, though none of these allegations has been supported by fact-finding efforts.

This is an extraordinary bucking of GOP leadership, which had hoped to avoid objections. However, Majority Leader Mitch McConnell did, according to senators, tell them privately to vote their conscience.

More than 3 million Georgians have already voted in the Jan. 5 runoff election, a figure that both smashes the previous turnout record for a statewide runoff in the Peach State and exemplifies the urgency of the dual Senate runoffs that will determine which party controls Congress's upper chamber.

According to Georgia Votes, which is analyzing data from the secretary of state's office, 3,001,017 voters had cast ballots in the runoff election following the last day of the three-week advance in-person voting period. Of those votes, 928,069 are absentee by mail and 2,072,948 are from in-person early voting.
