IRS Inspector General Probes Treatment of Tea Party Activist

Martha Boneta is a thorn in the side of environmental groups

The Inspector General of the U.S. Treasury Department is investigating whether an environmental group pressured the Internal Revenue Service into auditing a Virginia farmer and tea partier, according to attorneys, policy analysts and other sources familiar with the case.

But the investigation has not discouraged IRS auditors, who are expanding their audit of Martha Boneta in what has become a high-profile dispute over property rights.

Boneta told The Daily Caller in an interview that she has been asked to submit "reams and reams" of new information in addition to the original audit request.
