WASHINGTON, D.C. -- Conservative groups outraged at the IRS demanded action today.
In Washington, the groups and some lawmakers are accusing the IRS of committing a crime.
Conservative groups testifying on Capitol Hill said the IRS targeted them for no other reason than their political preferences. They said they were stunned by the IRS' follow-up questions when they were applying for tax-exempt status.
The House Ways and Means Committee is split over what motivated the IRS.
"By asking you hundreds of questions about your personal lives? That's efficiency? I don't think so," said Rep. Dave Reichert (R), Washington's 8th district.
"This has nothing to do with red versus blue," said Rep. John Lewis, (D), Georgia's 5th district.
The leader of the National Organization for Marriage accused the IRS of giving donor lists to the media in violation of federal law. The group advertised against gay marriage -- especially in California.
"It's not like someone just dropped our paperwork on the sidewalk; this wasn't inadvertent. They deliberately provided our donor list to our opponents seeking that for a long time," said John Eastman, chairman of the National Organization for Marriage.
The committee promised more digging. Tea Party groups made their wishes clear.
"This needs to be remedied civilly or criminally," said Karen Kenney of the San Fernando Valley Patriots.
"Don't stop until you get to the bottom. You need to get rid of this cancer," said Becky Gerritson of the Wetumpka Tea Party.
There are multiple investigations of the IRS under way in Washington right now.
On Thursday, the House Oversight Committee will hold a hearing about questionable spending by the IRS.
