Trump rallies supporters in Harrisburg on 100th day

Touting key points of his policy agenda on his 100th day in office, President Donald Trump addressed a crowd that nearly filled Harrisburg's 7,000 seat Farm Show Arena to capacity on Saturday night.

Touching on subjects including immigration reform, decreasing federal regulations, renegotiating trade deals, expanding the military and investing in clean coal, Trump addressed a sea of red hats, red shirts and signs of support.

He also took direct aim at the media.

Referencing the White House Correspondents’ Dinner occurring in Washington at the same time, Trump said he’d rather be in Harrisburg with “much better people.”

The crowed booed as Trump spoke of the “disgraceful” media attending the “very, very boring dinner.”

Trump's comments on economic revitalization met with cheers from the Pennsylvania crowd, a state ravaged by declines in coal and steel.

Pennsylvania steel will be "the spine of America,” Trump said. He also said he has issued a new order to hire American and buy American.

“Our jobs will come back home. Our factories will come roaring back to life,” he promised.

Trump at one point read poetry – “The Snake” by Oscar Brown Jr. — to the crowd to make a point about immigration.

The Chicago Tribune writes of the song, “based on one of Aesop's fables, ... It's an allegory, so it can be about a lot of situations where one party unsuspectingly lets in an evildoer and then gets hurt.”

Although supporters dominated the audience, there were some incidents involving protesters.

After the rally, mounted police cleared the area in front of the Farm Show Complex, taking at least one woman into custody.

During the rally, one protester, a white man, was tackled by police.

"That's right, get him outta here," Trump said.

Earlier in the day, addressing a small group of protesters, Harrisburg’s mayor, Democrat Eric Papenfuse, criticized Trump for the rally, saying, "He is giving a speech to his base, to his paid supporters, right in the echo chamber of pure, partisan base. What an opportunity missed."

Later, a crowd of approximately 200 protesters marched outside the Farm Show Complex, shouting, "We're going to beat back the Trump attack."

After marching nearly a mile, protesters obeyed a police order to stop when they approached the complex. "Stand up; Fight back," they chanted.

Before attending the rally, Trump toured the Ames factory in Camp Hill. Ames has manufactured shovels since 1774, The Associated Press reports.

PennLive.com reports that workers gathered in the factory cheered the president and shouted "USA."

Trump was at the factory signing an order that will direct the Commerce Department and the U.S. trade representative to conduct a study of U.S. trade agreements, according to The Associated Press.

Of the thousands of supporters in attendance at the rally, some had waited for hours to see Trump.

First in line were William and Cia Malater, from upstate New York. It's their seventh Trump rally, and it's the fifth time they have been first in line.
