U.S. Senate Majority Leader Harry Reid charged Thursday that presumptive Republican presidential nominee Mitt Romney paid no taxes for a decade.
In a speech on the Senate floor, Reid, D-Nev., called on Romney to release more tax returns, the Los Angeles Times reported.
"Let him prove that he has paid taxes, because he hasn't," Reid said.
"Mitt Romney makes more money in a single day than the average middle-class family makes in two years or more," he added.
Reid has provided no proof for his repeated statement about Romney's taxes.
In a conference call Wednesday with Nevada reporters, Reid said the burden of proof is on Romney to show that he paid taxes.
Romney has released his 2010 return, filed in 2011, and has said he will release his return for last year. But the candidate, whose father, the late George Romney, pioneered the political practice of financial disclosure, has refused to release older returns.
Eric Fehrnstrom, a Romney spokesman, said in an appearance on Fox News that Reid's charge about Romney not paying taxes is "baseless" and "untrue." Romney has said he has always obeyed the law in his tax filings.
