The Internal Revenue Service, under pressure after admitting it targeted anti-tax Tea Party groups for scrutiny in recent years, also had its eye on at least three Democratic-leaning organizations seeking nonprofit status.

One of those groups, Emerge America, saw its tax-exempt status denied, forcing it to disclose its donors and pay some taxes. None of the Republican groups have said their applications were rejected.

Progress Texas, another of the organizations, faced the same lines of questioning as the Tea Party groups from the same IRS office that issued letters to the Republican-friendly applicants. A third group, Clean Elections Texas, which supports public funding of campaigns, also received IRS inquiries.
