Sen. Kamala Harris participated in two get-out-the-vote events in Pennsylvania this afternoon, a canvass launch in Luzerne County and a drive-in rally focused on Latino voters in Lehigh Valley, as Democrats pour their efforts into the state Trump narrowly won in 2016 in their final full day of campaigning.

In Luzerne County, Harris spoke to a crowd of 76 people about the importance of Pennsylvania to their path and told supporters there that Pennsylvania will determine the outcome of the election.

"That's why we're all here and keep coming back -- because we care about Pennsylvania and because Pennsylvania's gonna determine the outcome of this election," Harris said. 

Without mentioning Trump by name, Harris also hinted at the president's threats of legal action following the election, describing them as efforts to suppress the vote and intimidate voters.

"We know that there are a lot of folks around the country, including you know who, who have been trying to openly suppress the right to vote, to intimidate, to make it difficult, to make it confusing," she said, telling supporters it's all the more reason to make sure their ballot is cast and counted. 

Vice President Mike Pence at an afternoon rally in Erie shared the senator's sentiment on the importance of Pennsylvania, telling his crowd of supporters that "the road to victory goes right through the Keystone state."

The former vice president, at his first of three events barnstorming Pennsylvania, shared his belief that "what happens tomorrow is going to determine what this country looks like for a couple of generations" and hammered home his "Scranton vs. Park Avenue messaging" for the union crowd.

"I've never forgotten growing up in a hardworking family in Scranton," Biden began. "The lesson that Donald Trump has never learned because he can only see the world from Park Avenue. He can't see what families like yours and mine have gone through. So he refuses to do the work to get this virus under control."

Biden ticked through his promises to reward work not wealth, and once again hit back at Trump on fossil fuels, saying he "never" said he would ban fracking.

"And by the way, no matter how many times Trump tries to lie about it. I will not ban fracking, never said I would. But I'm going to end Trump's incentives to send jobs overseas," Biden said. 

Biden also punched up his attack on Trump reportedly calling military service members "suckers" and "losers," according to reporting in The Atlantic, saying that it is Trump who is the loser.

"The way he talked about our veterans being losers -- losers. What's this guy all about?  Who is he? He doesn't understand what's going on," Biden said, raising the service of his late son Beau, who was awarded a Bronze Star.

"He came home and he died of cancer but he came home and guess what? And guess what? He was no loser. Trump's a loser."

After he finished his remarks, Biden played the part of proud grandfather, bringing four of his grandchildren traveling with him on stage and adding, "They're proud to be here with you. I've been bragging about Pennsylvania."

As coronavirus cases rise across the country on the eve of Election Day, President Trump has invited about 400 people including family, White House staff, campaign aides and top supporters to the White House on election night, sources tell ABC News.

As of now the event is planned to be indoors, sources said.

The original election night plan for Trump was to be at his hotel on Pennsylvania Avenue, but after the District threatened take action if there was a mass gathering -- as coronavirus precautions in place currently restrict crowd sizes -- Trump aides made the move down to the White House.

The president himself has speculated he could still pop by the hotel to visit other supporters.

Federal District Judge Andrew Hanen has rejected a Republican effort to invalidate roughly 127,000 drive thru votes cast in Harris County, Texas, saying he believes the plaintiffs who brought the case did not have standing to sue -- a major victory to Democrats and blow to Republicans.

The elections office of Harris County, the most populous county in the state which includes Houston and the surrounding area, argued it got state approval for the voting process back in June amid safety concerns with voting in a pandemic. Republicans, unsuccessfully, argued the Harris County clerk was acting on his own by implementing the practice.

The 127,000 drive-thru votes account for roughly 10% of the total early vote turnout in Harris County, and the ruling ensures the votes will be counted.

Judge Hanen didn't give strong indications during questioning which way he was leaning. While he began the hearing telling the Republican plaintiffs that they have a steep uphill battle to persuade him to invalidate the ballots, he also pressed the counsel for the Harris County clerk to answer what the county would do in if he did rule drive-thru voting is illegal and what that would mean for their plans to continue offering drive-thru voting on Election Day.
