(CNN) - Sen. John Kerry's office took issue with Mitt Romney on Monday, saying the presumptive GOP nominee was wrong to use the Democratic senator and his wife as an example in the latest swirl over Romney's refusal to release more tax returns.
David Wade, Kerry's current chief of staff, said in a statement that Romney's team has long been "conjuring up false and convoluted alibis," including Kerry's 2004 tax disclosure, as an excuse for not releasing further tax returns of his own.

Monday morning, Romney made headlines when he mentioned Kerry and his wife, Teresa Heinz, as precedents for deciding not to release more than the two years' of tax documents Romney has already made public.
"John Kerry ran for president and his wife, who has hundreds of millions of dollars, she never released her tax returns," Romney said on Fox. "Somehow this wasn't an issue."
However, Kerry's office was quick to point out that Teresa had in fact released the first two pages of her most recent tax return in 2004, revealing that she took in about $5 million in 2003 and paid approximately $750,000 in taxes, according to the information.
Wade, who served as Kerry's national spokesman in the 2004 presidential campaign, added that Romney also needed to get his facts straight about the Massachusetts senator.
While Romney has previously said that he's releasing the same level of tax information as Kerry did in 2004, the senator's office said by the time Kerry was running for president, he had already made public 20 years of tax information from previous Senate races-not two years' worth. That number included five years of tax returns released during his 2004 White House bid.
"As Sen. Moynihan once said, people are entitled to their own opinions, but they're not entitled to their own facts," Wade said. "Facts matter."
Over the weekend, Democrats and some Republicans continued to push Romney to release more tax information, saying having further documentation of Romney's financial holdings would shed light on offshore investments and overseas accounts.
Romney released tax returns from 2010, and put out an estimate of his 2011 information in April. He filed an extension with the Internal Revenue Service to file after the April deadline, and has vowed to release the official documents when they're completed by his accountant.
