"Trump would take us back to where we were before the crisis. He'd rig the economy for Wall Street again. Well, that will not happen on my watch," the presumptive Democratic nominee said, referring to Trump's plan to "wipe out the tough rules" put on big banks after the 2008 recession.
Clinton mentioned Massachusetts Sen. Elizabeth Warren numerous times in the speech and praised Warren's role in creating the Consumer Financial Protection Bureau, which Trump has said he would dismantle.
"He calls himself 'the king of debt.' And his tax plan sure lives up to that name. According to the independent Tax Policy Center, it would increase the national debt by more than $30 trillion over 20 years. That's 'trillion,' with a 'T,'" she said.
The former first lady quoted Trump throughout her speech and said that although he is "the king of debt," he has no plan to make college debt free. Trump was quick to respond to her speech on Twitter.
Clinton told supporters that while writing this speech and the one on foreign policy that delivered a few weeks ago, she had "to look twice" because she could not believe Trump's words and his plans if he is elected.
"Under Donald Trump's plan, these Wall Street millionaires will pay a lower tax rate than many working people. And of course, Donald himself would get a huge tax cut from his own plan. But we don't know exactly how much, because he won't release his tax returns," Clinton told supporters at the Fort Hayes Metropolitan Education Center in Columbus. She then asked, "What's he afraid of?"
Trump recently said that his economic policy would implement many of the methods he used in his real estate business. But Clinton pounded his economics throughout the 45-minute speech and said he has "no real strategy for creating jobs, just a string of empty promises."
"Let's take a look at what he did for his business," said Clinton. "He's written a lot of books about business. They all seem to end at Chapter 11."
Clinton also brought up the Trump University lawsuits, saying that the things has promised to do as president are the same things he promised to customers enrolled in his seminar program. She said that even if she weren't running for president, she would have the same view of his policies because she believes that he is solely focused on making money for himself.
"He makes over-the-top promises that if people stick with him, trust him, listen to him, put their faith in him, he'll deliver for them. He'll make them wildly successful. And then everything falls apart, and people get hurt."
Her address today was the first of back-to-back speeches that she is delivering on the economy. Tomorrow in Raleigh, North Carolina, the former secretary of state will give a speech that, aides say, will be focused more directly on economic policy than on the presumptive Republican nominee.
Before her remarks today, Clinton's campaign launched a website, ArtOfTheSteal.Biz (a play on Trump's best-selling book "The Art of the Deal"), highlighting some of Trump's less successful business ventures. The campaign also released a web video about him titled "Bad Businessman."
Trump has scheduled a speech focusing on Clinton tomorrow morning in New York City.
