President Trump landed in Montoursville, Pa., for his final Pennsylvania rally Saturday night in the lead-up to the election after announcing he signed an executive order earlier in the day to protect fracking.

Trump started the last of four events in the state by hitting Democratic presidential nominee Joe Biden for plans to raise taxes by $4 trillion, highlighting $2 gas prices and touting the employment rate.

"In the past five months, we've created 1.4 million jobs," Trump said.

The president also referenced a Gallup poll that said Americans are happier today than they were under the Obama-Biden administration. 

His comments came the same night former President Obama said that under his administration manufacturing in the U.S. went up 15% during his second term, while it reportedly went up 1% during Trump's term in office. 

Trump reminded the crowd in Montoursville of his announcement at an earlier Pennsylvania rally that he signed an order to "strongly protect your states fracking and energy industry." 

Knife in the back

Trump said Biden had "twisted his knife into the backs" of Pennsylvania when it came to manufacturing in the Keystone State.

The Wall Street Journal reported Tuesday that Trump was weighing such an order, which would gather information from the Office of the U.S. Trade Representative and the Treasury Department about how fracking affects the economy and trade and highlight the consequences of eliminating the technique, which employs drilling to extract gas and oil.

"Moments ago I signed an executive order to protect Pennsylvania fracking and block any effort to undermine energy production in your state," Trump told a crowd in Butler, Pa., earlier Saturday. 

"So if one of these maniacs come along say end fracking, I signed it on the beautiful Marine One," the president said.

In addition, Trump would ask officials from the Energy Department and Interior Department to advise on how technology or land management could be used to expand the use of fracking, but the details at that time were still being finalized. 

Trump capitalized on his opponent's wish to "transition" away from the oil industry during an earlier stop in Reading, Pa., telling supporters  Biden would "abolish" fracking. 

He said the former vice president had flip-flopped on fracking, a major industry in the key swing state. 

"He goes for a year 'there will be no fracking,' then he comes to Pennsylvania. Listen, we have a million jobs for fracking we've got $2 gasoline," Trump said. "He's like 'let me just change my [position]' and he's never questioned about it from the fake news."

Biden said in March at a Democratic primary debate, “No more no new fracking.”

In October at the final presidential debate, Biden said: “I do rule out banning fracking because the answer we need ... We need other industries to transition to get to, ultimately, a complete zero emissions by 2025.”

Biden also has repeatedly said he would raise taxes only on people who make more than $400,000 a year. 

"Joe Biden will shut down your economy, you're already shut down in Pennsylvania," Trump said Saturday.

Ballot-count extension

Trump then said the "only way" he could lose Pennsylvania is through an extension allowing ballots to be counted through Nov. 6. 

"What's the extension all about?" Trump asked. "Wouldn't you like to hear November third? We win, we lose?"  

The Supreme Court on Wednesday ruled that Pennsylvania can count mail-in ballots until Friday after Election Day, despite Republican objections.

The high court denied a GOP request to fast-track a decision on blocking vote counting after Nov. 3 - meaning that as long as ballots are postmarked by Election Day, they can arrive three days after Tuesday and still count. 

"We get many disappointing opinions from the Supreme Court. They talk about we control Supreme Court, we don't control Supreme Court," Trump said. 

'Save the American Dream'

President Trump told supporters in Bucks County, Pa., that they have the chance to “save the American dream” by reelecting him Tuesday -- while warning of “corrupt forces” seeking to replace him with  Biden.

“This is the state where the story of American Independence began – it is the state where the American Constitution was signed -- think of that – and three days from now this is the state that will save the American Dream,” he said too loud cheers from supporters.

He presented the election as a choice between being ruled by a “corrupt political class,” or government by the people. Touching on the populist tone he took in the 2016 campaign, he accused the political class of "bleeding the American people dry" and letting American cities die.

“No one embodies this betrayal and treachery more than Joe Biden," he said. "And worst of all the suppressed media and Big Tech refuses to cover the crime."

He touted his administration's moves on the coronavirus and also bringing the economy back from the downturn associated with the virus.

Trump accused Biden of wanting to lockdown the country again -- something Biden has floated if scientists recommended it, but has recently said he wouldn't do.

"Biden's plan will destroy America, my plan will destroy the virus and make America greater than it's ever been," he said.

Trump spoke at four events in Pennsylvania on Saturday. On Monday, the president will make stops in North Carolina, Pennsylvania and Wisconsin and host two events in Michigan, ending his whirlwind of campaigning on the eve of the election in Grand Rapids, a repeat of his finale in 2016. 

Biden's camp plans to barnstorm Pennsylvania on Sunday and Monday, with Biden, his wife, Jill Biden, and running mate California Sen. Kamala Harris and her husband, Doug Emhoff, fanning out across Pennsylvania to ask for last-minute votes.
