GREENSBORO, N.C. — Hillary Clinton emphasized her record of public service and proposals aimed at assisting working families in a campaign rally Thursday, returning to the campaign trail after a bout of pneumonia that she said gave her time to “sit down” with her “thoughts” and reflect on what matters most.

“I’ll never be the showman my opponent is, and that’s OK with me,” said Clinton, citing Donald Trump’s Thursday appearance on The Dr. Oz Show. “I sweat the details” and “I am going to deliver for you and your family,” she said at the campaign event held at the University of North Carolina at Greensboro.

Similar to her nominating convention in Philadelphia, Clinton focused on her biography over lobbing attacks against Trump, including her work on behalf of the Children’s Defense Fund as an Arkansas lawyer and her plans to help working mothers with paid sick and parental leave, as well as equal pay for women.

Trump releases medical report, says he's in great health

Clinton did not entirely pull her punches, though.

This week, Trump unveiled his own proposal for paid leave for new mothers, which the Democratic presidential nominee called “half-baked,” noting it follows “decades of ignoring and putting down moms.” She asked voters to “hold me accountable for my ideas and my opponent accountable for his.”

Clinton has been resting at her home this week after being diagnosed on Friday with what her doctor described as a mild bacterial pneumonia.

During an interview that aired Thursday morning on the Tom Joyner radio show, Clinton pledged to release more medical records beyond a Wednesday letter from her doctor detailing her pneumonia and routine lab tests that indicated normal results.

"We really want to respond to legitimate questions that people might have," Clinton said. "I’m very touched by the concern that’s been set forth about my health."

Clinton is seeking to shift the focus back to her campaign message — "stronger together " — as both national polling averages and surveys in Ohio and Florida show Trump has erased her earlier advantage.

North Carolina, site of Thursday's event, has traditionally been Republican-dominated, yet with changing demographic and politics, it is a place where Clinton thinks “she can compete,” said spokesman Nick Merrill.

During her speech, Clinton asked the public to focus on issues over “chatter” that has “not all that much to do with what the next president has to do,” including creating jobs and making college affordable.

“People accuse me of all kinds of things,” said Clinton. “But nobody ever accuses me of quitting.”

After the health episode, the campaign is facing questions about transparency. Clinton aides initially gave differing explanations of her condition, including that she was simply "overheated."

It was only after amateur video footage of her stumbling into her van emerged that the campaign disclosed her pneumonia diagnosis.

Fielding questions from members of the press following her Thursday speech, Clinton was asked about reports that her running mate, Virginia Sen. Tim Kaine, was not informed of her pneumonia diagnosis Friday.

“We communicate,” she said, without elaborating on how often, adding that her “senior staff” knew of her condition.

“This was an ailment that many people just power through, and that’s what I thought I could do as well,” Clinton said. Regarding her slow disclosure to the public, Clinton said: “My campaign has said that they could have been faster, and I agree with that. … But I have to say, from my perspective, I thought I was going to be fine.”

In the Greensboro speech, Clinton said taking time away from campaigning wasn't her initial inclination, but added that it proved to be beneficial.

“I’m not great at taking it easy under ordinary circumstances,” said Clinton. “But, with just two months to go until Election Day, sitting at home was pretty much the last place I wanted to be,” she said. “Turns out having a few days to myself was actually a gift."
