Trump's first rally of the day was in Allentown, in Pennsylvania's Lehigh County and the larger Lehigh Valley region in the northeastern part of the state. 

Hillary Clinton won 50% of the county in 2016, with roughly 7,600 more votes than Trump. But he won nearby Northampton County by 5,400 votes, on the way to winning Pennsylvania by roughly 44,000 votes. Given that Northampton County is one of the few pivot counties that went for President Obama in 2008 and 2012 before turning to Trump, the president's visit represents an effort to keep his supporters in the suburbs in play.  

The area was represented by U.S. Rep. Pat Meehan, a Republican, from 2011-2018, until he resigned amid a sexual harassment scandal. After redistricting, the area is now represented by Rep. Susan Wild, a Democrat. 

His second stop brought him to Lititz in Lancaster County where he easily defeated Clinton by roughly 50,000 votes four years ago. He also won with roughly the same margin as Mitt Romney did in 2012, though more people voted in the 2016 race for both candidates than four years prior. 

Pence has also visited the area twice since August. 

Trump holds a third rally in Martinsburg, in Blair County, where he won roughly 75% of the vote in 2016. The county in central Pennsylvania between Harrisburg and Pittsburgh is a reliably conservative region of the state -- where Trump needs to run up his numbers to help keep Pennsylvania in GOP hands in November.

An energized President Trump declared Pennsylvania his must-win state at the first of three rallies there today, slamming Joe Biden for staying off the campaign trail today and urging the audience in Allentown to get out the vote.

“We win Pennsylvania, we win the whole thing,” Trump said to a crowd of closely-packed supporters, many without masks. "You have to get out there."

He opened by railing against Biden for saying at last Thursday's debate that he would transition from the oil industry over time and end fossil fuel subsidies, Trump telling Pennsylvanians their livelihoods are at risk as the state is the second largest producer of natural gas behind Texas. 

"So will you remember that, Pennsylvania, please?" Trump said, after playing a video of spliced news clips highlighting his administration's accomplishments and Biden’s past answers to questions on fracking and relations with China. 

On the coronavirus pandemic, Trump claimed he "saved over two million lives," likely referring to an early model which predicted deaths would only be that high if no attempts were made by the government, nor individuals, to alter their behavior to control the pandemic. The U.S. death toll, instead, is on track to surpass the 240,000 maximum prediction Trump's task force gave in the spring for the year.

As cases are on the rise across the country -- with records being set in recent days -- hospitalizations and deaths are up in many areas, and experts have repeatedly warned the situation would get worse leading into the fall and winter. But Trump lamented against media coverage of the surging cases suggesting it's a ploy to hurt his reelection chances. 

“By the way, on November 4th you won't be hearing so much about it. COVID, COVID, COVID, COVID,” he said, repeating a line he's now highlighting. 

Providing no evidence, Trump also claimed that his campaign was trying to find a venue for this event up to the last minute because Pennsylvania Gov. Tom Wolf, a Democrat, made it “impossible” for the president to host campaign events in the state, sending a direct warning to Wolf.

"I'll remember it, Tom. I'm gonna remember it, Tom. 'Hello, Mr. President, this is Governor Wolf, I need help, I need help.' You know what? These people are bad,” Trump said, adding the false claim that Wolf will be counting ballots in the state. "We're watching you."

Trump continued his pitch to suburban women in Pennsylvania, a demographic he is struggling with in the polls, but insisted he’s "saving the suburbs." 

“They want two things. They want to leave their house alone. They don't want a five-story project next to them -- or could be higher," Trump said. “They don't want to have antifa and anarchists running through the streets, okay? So if they agree with what I just said, I have a feeling they are going to be voting for Trump."

With a backing from white, moderate and suburban women in Pennsylvania, it is Biden who has an 8% advantage with the group in the state, according to a recent ABC News/Washington Post poll.

Vice President Mike Pence is not expected to preside over Judge Amy Coney Barrett’s Senate vote this evening unless his vote is needed, multiple sources tell ABC News. 

Barrett has the GOP votes to be confirmed so it’s unlikely that Pence’s tie-breaking vote will be needed.

According to his schedule, Pence will be back in town from a Minnesota campaign stop during the time of the vote, which is expected at 7 p.m.

Shortly after White House communications director Alyssa Farrah said that Pence would be presiding over the Senate vote, White House chief of staff Mark Meadows told reporters during a gaggle that Pence showing up was "in flux." Over the weekend, Pence "as vice president, I am president of the Senate. And I'm going to be in that chair cause I would not miss that vote for the world!"

It’s unclear if Pence plans to attend a likely White House South Lawn this evening to celebrate Barrett's confirmation and swearing-in.

The change comes as five people in Pence’s orbit have tested positive for the coronavirus, though Pence was cleared by doctors to continue to travel as “essential personnel,” according to his office.
