Obama labor secretary-nominee faces tax questions | Politics | Reuters

A U.S. Senate panel delayed its vote on Labor Secretary-designate Hilda Solis after the newspaper USA Today reported that her husband paid about $6,400 on Wednesday to settle tax liens that had been outstanding against his business for as long as 16 years.

"We reviewed her tax returns and her tax returns are in order," Gibbs said. "She's not a partner in that business, so we're not going to penalize her for her husband's business mistakes."

Asked if Solis' husband paid the taxes at the prompting of the White House, Gibbs said: "I think he paid the liens back because he owed the taxes. ... The White House believes that if you owe taxes, you should pay them. But at the same time, this obviously is a business that she's not a partner in and we're not going to hold her responsible for."
It wasn't her taxes but her husbands however it begs the question that at some point, didn't she have to know about it?

It seems that she also violated house ethics rules by not reporting that she was the treasurer of an organization she was lobbying for while a representative.
