'Mike Lee is here, but I'm a little angry at him': Moment President calls out senator during Georgia runoff rally for refusing to join Kelly Loeffler and back Ted Cruz's 'Dirty Dozen' push to overturn election

President Donald Trump is ramping up pressure on Republican senators to join their colleagues in the effort to overturn Joe Biden's election victory.

And he's doing it publicly and bluntly.

Trump targeted Senator Mike Lee on Monday night, announcing he's 'angry' at the Utah Republican at a campaign rally in Georgia for the two Senate candidates in that state.

'Mike Lee is here, but I'm a little angry at him,' Trump said at the event.

His comments came after Lee announced he didn't support objecting to the election results when Congress meets on Wednesday to certify them. Lee's Republican colleagues, Senators Ted Cruz and Josh Hawley, are leading the objection charge in the upper chamber.

But Lee sent a letter to his Republican Senate colleagues explaining his lack of support in challenging the election results. President-elect Joe Biden won the electoral college with 306 votes to Trump's 232.

'With respect to presidential elections, there is no authority for Congress to make value judgments in the abstract regarding any state's election laws or the manner in which they have been implemented,' Lee wrote.

But other senators are joining the effort, including Republican Senator Kelly Loeffler of Georgia, who is on the ballot in Tuesday's special election in that state.

Trump, who held a rally for her and fellow Republican Senator David Perdue, also on the ballot, Monday night, praised the two for supporting the objection effort.

'Pleased to announce that @KLoeffler & @sendavidperdue have just joined our great #StopTheSteal group of Senators. They will fight the ridiculous Electoral College Certification of Biden. How do you certify numbers that have now proven to be wrong and, in many cases, fraudulent!,' the president tweeted on Tuesday morning along with an encouragement for Georgians to vote for them.

There is one problem, however. Perdue is no longer a sitting senator. His term expired January 3 and the winner of Tuesday's contest will be take that Senate seat so he is not eligible to participate in Wednesday's certification process.

Loeffler, in contrast, was appointed to fill a vacant seat so she will hold it until the results of the special election are certified.

When Congress meets in a joint session at 1 p.m. on Wednesday, Trump's allies in the House are looking to object to the results from six states: Arizona, Georgia, Pennsylvania, Michigan, Wisconsin and Nevada.

But senators are looking at only joining in the objections for three or four, Politico reported, primarily Arizona, Georgia, and Pennsylvania.

Both a senator and a congressman must object for it to be considered.

It's unclear how long the process to certify the electoral college results will take.

Each state's tally is read in alphabetical order and any objection must be raised at the time. Then lawmakers head to their respective chambers for two hours of debate before a final vote on the objection. If multiple states garner objections, the process will go into Thursday.

However, the senators weren’t excited about debating past midnight, Politico reported, in a sign the effort may lose steam if none of the objections are sustained.

And the odds of that happening are slim.

For a state's results to be dismissed, majorities of both chambers have to vote to sustain the objection. If one chamber votes to toss the state's votes and the other doesn't, the objection is dismissed.

The Democratically-controlled House is unlikely to support sustaining an objection, meaning the states' results will stand and Biden will ultimately be declared the winner.

Additionally, the Republican-controlled Senate isn't likely to vote in favor of an objection, either. The GOP has a slim margin in the upper chamber and a number of Republican senators have voiced their objections to the objection process.

The low down on how Congress certifies the Electoral College vote

At 1:00 p.m. on Wednesday, Senators and Representatives will gather in the House chamber for a Joint Session of Congress to count and certify the electoral college ballots.

Joe Biden defeated President Donald Trump by 306 electoral votes to Trump's 232.

But the constitution calls for Congress to certify the results, in a process that has become largely procedural. It is very difficult to over turn an election and it has never happened in American history.

Republicans, however, have vowed to object to the electoral college results, dragging out the certification process and putting on a grand display of theater that will likely please the president.

Here's how the day will play out:

The process is presided over by the president of the Senate, which is Vice President Mike Pence.

Pence will open the states' sealed certificates in alphabetical order and hand them them to one of four 'tellers' — a Republican and a Democrat from each chamber of Congress - who will announce how each state voted.

As each state's result is read, Pence will ask whether any member of Congress wishes to raise an objection.

At least one member of the House and one member of the Senate must object for the objection to stand. The law also states the objection must be in writing.

If the objection is recognized, the lawmakers go to their respective chambers to debate the matter for up to two hours.

Then the House and Senate each votes on whether to sustain the objection - which would dismiss the state's votes - or reject the objection.

For a state's results to be dismissed, majorities of both chambers have to vote to sustain the objection. If one chamber votes to sustain the objection and the other doesn't, the objection is dismissed and the state's electoral college results stand.

The Democratically-controlled House is unlikely to support sustaining an objection, meaning the states' results will stand and Biden will ultimately be declared the winner.

After the objection is voted on by each chamber, the joint session reconvenes and continues with the count. If there's another objection to a different state's vote, the process is repeated.

President Trump's allies are looking at challenging three states: Arizona, Georgia, and Pennsylvania, which could go into the early morning hours of Thursday.

'At the end of the day, which could be the middle of the night, Joe Biden and Kamala Harris will be officially declared the next President and Vice President of the United States,' Speaker Nancy Pelosi wrote to Democratic House members on Monday.

After the votes are recorded from all 50 states and the District of Columbia, the vice president declares who has received the requisite majority of electoral college votes. That announcement finalizes the election.

WHAT IF THE OBJECTIONS ARE SUSTAINED?

If, by some remote chance, an objection is sustained, Trump and his allies hope that will result in the electors being thrown out, ultimately bringing Biden's electoral count below the 270 needed to win.

If all three state challenges are successful, Biden would have 259 electoral votes, throwing the election to the House of Representatives to select the next president.

Under the 12th Amendment to the Constitution, each state congressional delegation gets one vote.

While Democrats control the House, Republicans control the majority of state delegations, which is how Trump hopes to be 'elected.'
