The inspector general's report found that Wilkins' office had sent the exempt organizations determination unit on April 24, 2012, "additional comments on the draft guidance" for considering applications of tea party groups for tax-exempt status (PDF).
The connections between Wilkins' office and the inappropriate profiling of conservative groups are especially noteworthy because there are only two appointees of the president at the IRS: the commissioner and the chief counsel.
Cynics may view this controversy as typical when the House is in the hands of a different party than the president, but guess what?
The Democrat-controlled Senate's Finance Committee has also weighed in.
That committee has called for three things: a hearing, an investigation and a request to the IRS for documents.
Montana Democrat Sen. Max Baucus, the committee chairman, stated bluntly, "Targeting groups based on their political views is not only inappropriate, it is intolerable, unacceptable and cannot be allowed."
Baucus promised a bipartisan investigation and has been true to his word. When the first week of August arrived, Baucus and his GOP counterpart, Sen. Orrin Hatch of Utah, said the IRS failed to provide "most of the information requested by the Committee."
As chairman of the ethics watchdog group National Legal and Policy Center, I had filed a complaint with the IRS in May 2011 showing that a purported charity called the Barack H. Obama Foundation -- named for the father of President Obama and run by his half-brother, Malik Obama -- had been raising funds in the U.S. by falsely claiming to be an IRS-approved charitable group.
I submitted proof that the foundation was not tax-deductible and had never even applied for that status despite the fact that it had been fundraising for about three years.
In fact, one of the foundation's directors admitted that an IRS application had never been submitted.
There was compelling evidence suggesting that the foundation was raising money on the Internet by misrepresenting itself as being IRS-approved when it really wasn't.
Suddenly, the foundation rushed an application to the IRS in late May 2011.
In the short span of about a month, Lerner -- the same person who took the Fifth Amendment rather than testify before Congress -- gave the Obama Foundation its tax-deductible status.
And, the IRS made that status retroactive for three years.
Even more curious, several of the forms submitted by Malik Obama were stamped as being received by the IRS in July 2011. That's one month after Lerner approved the group's new tax status.
Generally, the approval process for charitable groups seeking tax-deductible status takes longer than it does for groups that merely want to be tax-exempt, such as most of the tea party groups.
In any case, there's a good chance this scandal could last a while.
Anyone who follows Washington scandals knows that investigations can take months, sometimes years.
That story broke during the presidential campaign of 1972. The president's press secretary dismissed it as a third-rate burglary. The investigation was slow because there was an active pushback from the Nixon administration and the people being investigated. The end finally came in August 1974, when President Nixon resigned.
