The Obama campaign still wants Republican presidential candidate Mitt Romney to release additional tax returns to prove he paid the correct amount of taxes.
It's an offer Romney has rejected. The former Massachusetts governor said the strategy of focusing on his finances is designed to draw attention away from real issues like the economy.
After weeks of hounding from the media and the Obama campaign, Romney did say he reviewed his tax returns.
"I did go back and look at my taxes and over the past 10 years," he said. "I never paid less than 13 percent."
Romney already released his 2010 taxes and has pledged to reveal last year's as well. But he's drawing the line there, despite charges from opponents that he has something to hide.
"The word's out that he hasn't paid any taxes for 10 years. Let him prove that he has paid taxes, because he hasn't," Sen. Harry Reid, D-Nev., said.
Romney responded saying the accusations against him are "totally false."
"I'm sure waiting for Harry (Reid) to put up who it was that told him what he says they told him," Romney said.
Meanwhile, both campaigns are talking about Medicare.
President Barack Obama recently launched a new ad defending his record on the program. Romney's campaign claims the president's plan siphons spending from Medicare without safeguarding its future.
"He raided to pay for Obamacare," vice presidential candidate Rep. Paul Ryan said. "President Obama's campaign calls this an achievement. Do you think this is an achievement? It's not."
Behind the scenes, the fundraising race is on. Romney has run ahead of Obama in terms of money for months now.
Romney raised $101 million in July along with the Republican National Committee. Obama's campaign and the Democratic National Committee raised $75 million.
Both Vice President Joe Biden and Ryan are also facing heat over their credibility.
Ryan found himself explaining prior requests for stimulus money for his district, even though he publicly opposed the funds.
The White House is also dismissing suggestions that Biden be replaced after a series of gaffes on the campaign trail, including a recent stop in Virginia where he claimed Romney's policies would "put y'all back in chains."
