GOP front-runner Donald Trump continues to fight for a popular-vote victory in Pittsburgh, Pennsylvania.

On Wednesday, Trump made his way to the David Lawrence Convention Center to outline his vision for America, if elected.

After asking about Joe Paterno, the late former football coach of Penn State University, Trump explained why the people of Pennsylvania should vote for him as the next president.

"We are going to bring back the coal industry and the steel industry,” said Trump.  “We're bringing it back.”

From jobs to the economy, Trump touched on a number of issues, including his plan to repeal Obamacare.

"Obamacare is a disaster,” said Trump.  “You look at your premiums, they are going up 25, 35, 45 percent.  Nobody understands, and you can't use it.  The deductibles are so high, you can't use it."

Trump also outlined his plan to build a wall along the U.S. and Mexico border, which he said will be paid for by Mexico.

After expressing his disdain for the media, Trump turned his attention to a protestor, who was quickly removed from the rally.

Despite leading Ted Cruz in delegates, Trump called the delegate system corrupt.

"It is a corrupt system; it's a weak system,” said Trump.  “You have to change it.”
