While some conservative groups have come forward to corroborate stories of politically motivated targeting by the IRS, many are also keeping quiet for fear of further retaliation.

“Talk about a chilling effect on speech,” said one person who requested anonymity. “I’m afraid to go on the record because of what the IRS might do to my group.”

The source was a member of a conservative nonprofit that applied for tax-exempt status with the IRS. After waiting nearly a year without any response, the organization reapplied under an innocuous name.

The Cincinnati IRS office—the same at the heart of the current scandal—approved the application in three weeks.

“At that point, we had a history,” the source said. “But as soon as we changed the name, it sailed through.”
