Akron -- At rallies in both Toledo and Akron on Oct. 3, Democratic presidential nominee Hillary Clinton addressed the economy and her Republican opponent's fiscal irresponsibility.

To a crowd of more than 2,500 people at Akron's Goodyear Hall, Clinton thanked Akron native and Cleveland Cavaliers star LeBron James for endorsing her over the weekend.

"I may become president, but he will be king of Ohio," she said, noting that he has given back to the Akron area's schools both financially and by inspiring younger generations to do good.

Clinton talked mostly about the economy, beginning with her father's small business and moving quickly to targeting Wall Street, making note of the Wells Fargo scandal.

"We will never let Wall Street wreck Main Street again," she said. "We should have a big, dynamic small business economy. But we are not going to let big business and big corporations call the shots anymore."

Included in her proposed economic plan are more rules governing big banks, increased credit for small businesses and boosting jobs across America through smaller businesses.

She called Republican presidential nominee Donald Trump's economic plan "trickle down on steroids," saying it wouldn't help average Americans, especially those in cities like Akron.

Over the weekend, the New York Times reported that Trump had claimed a loss of more than $900 million in a single year, according to his tax returns. The Times said that amount would have allowed him to avoid federal taxes for nearly two decades.

Clinton's newest ad uses Trump's comments about being a genius for losing almost $1 billion in the casino business by not paying taxes against him, asking the public, "If not paying taxes makes him smart, what does that make the rest of us?"

"What kind of a genius loses a billion dollars in the first place?" Clinton said, mocking Trump for his comment at the first presidential debate on Sept. 26 about being smart for not paying taxes.

"Zero taxes means zero for our vets, zero for our military, zero for Pell Grants to send young people to college, zero for health, zero for education," Clinton said at the Akron rally.

Trump, at a rally in Colorado on Oct. 3, said he "brilliantly used those laws ... legally used the tax laws to my benefit and to the benefit of my company, my investors and my employees."

U.S. Rep. Tim Ryan spoke before the Clinton rally, telling the audience about his Italian grandmother's words for people she didn't trust: They had "due facce," or "two faces."

"He says he wants to rebuild America, make it great again. Well, it would be a lot easier to rebuild American if you paid your taxes," Ryan said. "We're not even asking you to pay more -- just pay your taxes."

At the same time, the New York attorney general's office ordered the Trump Foundation to immediately stop fundraising in the state, saying it isn't properly registered to do so.

At his rally in Pueblo, Colo., and a forum in Virginia, Trump targeted Clinton's lack of comments on cybersecurity, a topic Clinton did not address at either rally in Akron or Toledo.

U.S. Rep. Marcia Fudge and Akron Mayor Dan Horrigan also spoke before the rally in Akron.

"As a proud father of three daughters, let me tell you: This is not just another election. I want a president who inspires my daughters, not one who demeans them; I want a president who motivates them to care about their fellow Americans, not one who teaches them to fear others," Horrigan said. "And I want a president who forevermore shows them that they can be anything they want in this life."
