UPDATE 8:04 p.m.:
President Trump belittled the so-called "Washington media" at a campaign-like rally held in Harrisburg, Pennsylvania, Saturday evening. Before a roaring crowd, Trump touted his accomplishments in the first 100 days in office while affirming that he "couldn't be more thrilled to be more than 100 miles away from the Washington swamp."
The ethos of the PA rally was eerily reminiscent of his days on the campaign trail. Chants of "USA, USA" echoed throughout the crowd. An angry protester got the attention of Trump. "Get him out of here!" he exclaimed to security officials.
Trump reminded the crowd of what was occurring simultaneously in Washington, D.C., claiming that the media was "trapped" at the dinner.
"A large group of Hollywood actors and Washington media are consoling each other in a hotel ballroom in our Nation's Capital right now," he continued.
Before moving on to other topics, Trump rated the press--assigning them a failing grade and referring to them as a disgrace.
Changing topics, Trump touted his past legislative accomplishments, but also hinted at what's yet to come. Specifically, he mentioned the Paris Agreement, saying he "will be making a big decision" on the international deal "in the next few weeks."
His remarks arrived the same day as tens of thousands of protesters took to the streets nationwide demanding that President Trump act on climate change.
Trump ensured to touch on challenges facing the working class--a large, decisive demographic in Pennsylvania.
He promised to bring "brand new Pennsylvania steel into the spine of America."
ORIGINAL STORY: President Donald Trump is marking his 100th day in office by talking tough on trade. He will mark the big day at a rally in Pennsylvania.
The White House says the president will sign an executive order Saturday that will direct his Commerce Department and the U.S. trade representative to perform a comprehensive study of the nation's trade agreements.
The aim is to determine whether America is being treated fairly by its trading partners and the 164-nation World Trade Organization.
The venue for the signing of the executive order is a shovel factory in Pennsylvania's Cumberland County.
In the evening, the president will appear at a rally in Harrisburg to cap the occasion of his first 100 days in office.
Some of the president's toughest critics are also marking the day on Twitter using the hashtag #100Days.
Nancy Pelosi wrote the president "doesn't care about jobs and empowering communities."
Sen. Tim Kaine said the president is "hurting American families."
