(CNN) – Sen. Harry Reid said nothing of his earlier claims that Mitt Romney had not paid taxes over a ten-year span in a Friday statement joining Democrats in responding to Romney's release of tax-related documents on Friday.
The Nevada Democrat and Senate majority leader called Romney's accounting "galling" and said the documentation "reveals that Mitt Romney manipulated one of the only two years of tax returns he's seen fit to show the American people – and then only to 'conform' with his public statements."

Meanwhile, President Barack Obama's campaign also released a statement on Friday saying the GOP candidate took advantage of "complex loopholes and tax shelters only available to those at the top."
Over the summer, Reid caused a stir when he claimed a source - who he has not named, but identified as an investor at Romney's former financial firm, Bain Capital - told him the GOP candidate did not pay taxes over a decade, though he did not specify which set of ten years were included in this claim.
In addition to his full 2011 returns, Romney released a letter from the accounting firm PricewaterhouseCoopers saying Romney had owed and paid taxes over the last 20 years. The letter said the average effective rate over that period was 20.2%, and the lowest rate was 13.66%.
Romney has said he was CEO of Bain Capital from 1984 through 1999, when he left to lead the Salt Lake City Olympic Games.
Reid referred to Romney's returns as completed by "accounting wizards" and charged in his Friday statement that the question remains, "what else in those returns has Romney manipulated?
"We already know Romney has money in tax havens in Switzerland, Bermuda and the Cayman Islands. What we don't know is why he refuses to be straight with the American people about the choices he's made in his financial life. When will the American people see the returns he filed before he was running for president?" he said in the statement. "Governor Romney is showing us what he does when the public is looking. The true test of his character would be to show what he did when everyone was not looking at his taxes."
Obama's deputy campaign manager Stephanie Cutter said in a statement that while Romney's Friday release "continues to mask Romney's true wealth and income from Bain Capital, leaving the American people in the dark about critical details about his finances, it does confirm that he continues to profit from millions of dollars invested overseas.
"These types of investments, the use of tax loopholes, and the resort to foreign blocker corporations enabling him to reduce his U.S. tax obligations, all raise basic and still unanswered question – why does Mitt Romney not just release the full returns, instead of the bare summary he has provided of the last 20 years, so voters can make their own judgments about Mitt Romney's finances?" Cutter continued. "As Mitt Romney's father said, candidates should release several years of returns, because one year could be a fluke. President Obama, Vice President Biden and nearly every other candidate in recent memory has met that test, but Mitt Romney continues to fail it."
