The head of the Internal Revenue Service told Congress on Thursday the agency isn't denying tax-exempt status to Tea Party groups because of their political views.

But IRS chief Douglas H. Shulman tells a House panel that his agency prides itself on being non-political. He says the answers the IRS is seeking are typical of the questions that it asks when determining whether a group is entitled to be tax exempt.

After the Ways and Means Committee hearing, Rep. Charles Boustany, R-la., told reporters he was dissatisfied with Shulman's response, saying groups feel their First Amendment rights are being violated.
