Watch Live: President Trump's Pennsylvania Campaign Stop

PENNSYLVANIA — President Trump was in Pennsylvania Thursday for his first rally in the crucial swing state since mid-May, intensifying his campaign as national attention is drawn to the largely virtual Democratic National Convention this week.

Trump will speak at the Mariotti Products Building in northeastern Pennsylvania's Old Forge at 3 p.m. The rally, just outside of former Vice President Joe Biden's childhood home in Scranton, comes hours before Biden is set to formally accept his party's nomination for president at the Democratic National Convention Thursday night.

The event itself is closed to the general public, but a live stream of event will be broadcast on Trump's official Youtube channel below.

"There is NO WAY a place like Pennsylvania can vote for the Radical Left and their puppet, Joe Biden, when they are against fracking, steel production, and just about everything else that Pennsylvania stands for," President Trump wrote on Twitter back in late July. "Likewise, Texas, and many other states!!!"

The rally comes a day following President Obama's own visit to the state, when he addressed the Democratic National Convention from the Museum of the American Revolution in Philadelphia's Old City Wednesday night. The speech was Obama's strongest rebuke yet of Trump, and focused on the threat Trump's attacks on mail-in voting posed to democracy.

"Donald Trump hasn't grown into the job because he can't," Obama said.

Trump's last visit to Pennsylvania was also to a northeastern Pennsylvania manufacturer, when he spoke at an Allentown medical equipment company in mid-May and urged Gov. Wolf to reopen parts of the economy.

Working class voters who felt ostracized by the Obama administration have long been pointed to as one of the reasons for Trump's victory over Hillary Clinton in Pennsylvania and other Rust Belt states in 2016. Biden's history in the area and the belief in the Democratic establishment that he can connect to blue collar Americans has fueled the optimism in his candidacy from the beginning.

Biden has held a consistent lead over Trump in polls in Pennsylvania since before he announced his campaign. As of Wednesday, he leads Trump by 6.4 points, 49.7 to 43.3, according to an aggregate of recent polls from RealClearPolitics. As Trump supporters note, this is only slightly larger than the poll lead which Hillary Clinton enjoyed in the state in the run-up to the 2016 election.
