If Melania Trump is first lady, she'll focus efforts on putting an end to bullying on social media.

In her first solo speech since the Republican National Convention, Melania Trump on Thursday called for an end to online bullying of children and teenagers, saying, it is "absolutely unacceptable when it’s done with no name hiding on the internet."

“Technology has changed our universe. But like anything that is powerful it can have a bad side. We have seen this already. As adults, many of us are able to handle mean words — even lies. Children and teenagers can be fragile. They hurt when they are made fun of or made to feel less in looks or intelligence. This makes their life hard and forces them to hide and retreat. Our culture has gotten too mean and too rough especially to children and to teenagers.”

"We have to find a better way to talk to each other, to disagree with each other, to respect each other," she continued. She did not make any reference to the fact that her husband has engaged throughout the campaign in bare-knuckled personal attacks on his political opponents, the media, random celebrities and a host of others.

Her speech in Berwyn, Pa. — a suburb of Philadelphia — was directed at suburban women, a group that could be critical if Trump wants to pull-off a win next week.

"People have asked me, if Donald is the President, what kind of First Lady will you be?" Melania Trump said. "It will be my honor and privilege to serve this country. I will be an advocate for women and for children."

Trump’s wife has stayed mostly out of the spotlight since her speech at this year’s Republican National Convention, which included a section taken directly from Michelle Obama’s 2008 convention speech. She was joined on the trail Thursday by Indiana Gov. Mike Pence's wife Karen — who gave a glowing introduction.

Melania Trump focused on her upbringing in Slovenia and making it to America.

"I'm an immigrant and let me tell you no one values the freedom and value of opportunity more than me," Melania Trump said. She said it took her 10 years to become a U.S. citizen. "Love for this country is something we immediately shared when I met Donald."

"He certainly knows how to shake things up — doesn’t he?" she asked, eliciting cheers from the crowd.

Washington Post-ABC News tracking polls released this week have Donald Trump losing white, college-educated women by roughly two dozen points. Mitt Romney won the group by 6 points according to exit polls.

One way the campaign has tried to appeal to suburban voters in Pennsylvania is to dispatch some of his less bombastic surrogates to the area. His daughter Ivanka Trump held a series of “coffee with Ivanka” events in the Philadelphia suburbs last month.

Pennsylvania is one of a handful of states critical to Donald Trump's election. Currently, Clinton leads by an average of 3 points, but polls over the last week have shown a tightening in the race.

“Pennsylvania is a state that we are confident winning. It’s a state (whose) makeup fully relates to Mr. Trump’s message as well as Mrs. Trump’s message,” Boris Epsteyn, a senior adviser to the campaign, told USA TODAY on Thursday.

The campaign has spent a significant amount of time in Chester County, a Philadelphia suburb, where the city of Berwyn is located.

It’s a county in battleground Pennsylvania full of white, college-educated voters, a demographic with which Donald Trump has struggled.
