(CNN) - Hillary Clinton said Tuesday she got heated over the weekend when she sharply criticized rival Barack Obama for distributing literature that she claimed misrepresented her positions on NAFTA and healthcare.
"I got a little hot over the weekend down in Cincinnati," Clinton said at a town hall event in Lorain, Ohio. "Because I don't mind having a debate. I don't mind airing our differences, but I really mind it when Sen. Obama's campaign sends you literature in the mail that is false, misleading and has been discredited.
"That is not the way to run a campaign to pick the Democratic nominee for president," she added, to applause.
On Saturday - only two days after declaring she was "honored" to share a stage at the CNN/Univision debate with Obama - Clinton angrily denounced two mailers his campaign was distributing in Ohio, one that described her as a supporter of NAFTA, and one that said she would force everyone to buy health insurance, regardless of ability to pay.
"Shame on you, Barack Obama," she said. "Enough with the speeches and the big rallies and then using tactics right out of Karl Rove's playbook. This is wrong, and every Democrat should be outraged." (Watch video: Clinton calls out Obama)
Obama denied Clinton's assertions that the claims in the campaign literature was false.
