He's even made the claim on the floor of the Senate (LA Slimes):
Senate Majority Leader Harry Reid took his jihad concerning Mitt Romney's personal finances to the chamber floor Thursday, repeating his unsubstantiated claim that the wealthy Republican paid no federal income taxes for 10 years.
...Reid's allegations, which he has refused to substantiate, are taking the issue to a new level.
The Democrat, in remarks to the Senate this morning, said "the word's out that he [Romney] hasn't paid any taxes for 10 years." Of course, that "word" has come from none other than Reid himself. Since last month, when he alleged in a Senate floor speech that Romney "basically paid no taxes in the prior 12 years," the Nevada lawmaker has continued to hammer away at the topic.
Reid has said he learned about Romney’s taxes earlier this summer from an investor in Bain Capital who, he said, called his office to pass along the information. The senator has refused to identify the investor and has acknowledged that he can't be certain about the veracity of the charges he's been spreading.
So "Dingy" Harry makes the allegation that he cannot prove, on the floor of the Senate, mind you, that the GOP front runner has not paid taxes for 10 years, even though Romney has released tax forms from 2010. It seems to me like Reid, the Democrats, and their media lapdogs want to distract from Obama, Reid & Pelosi's failed record over the last four years, and want Romney's tax returns for a fishing expedition.
But people who live in glass houses shouldn't be so quick to throw stones.
Why do I say that? Flashback to 2006 (AP via 24ahead).
Senate Democratic Leader Harry Reid collected a $1.1 million windfall on a Las Vegas land sale even though he hadn't personally owned the property for three years, property deeds show.
In the process, Reid did not disclose to Congress an earlier sale in which he transferred his land to a company created by a friend and took a financial stake in that company, according to records and interviews.
The Nevada Democrat's deal was engineered by Jay Brown, a longtime friend and former casino lawyer whose name surfaced in a major political bribery trial this summer and in other prior organized crime investigations. He's never been charged with wrongdoing - except for a 1981 federal securities complaint that was settled out of court...
Not only that, when Reid was asked about the land deal by the AP reporter, he hung up the phone.
Did Harry Reid break the law, even perhaps commit a felony, by profiting off of the sale of land which he did not own? What other shady things has "Dingy" Harry done? What other deals has he not disclosed?
