Matt K. Lewis of The Daily Caller points out that most reporters have neglected to report that the IRS is guilty not only of targeting conservative groups, but also of leaking NOM's private tax documents -- clearly a broader investigation is needed:

A little over a year ago, I reported that, ”It is likely that someone at the Internal Revenue Service illegally leaked confidential donor information showing a contribution from Mitt Romney’s political action committee to the National Organization for Marriage, says the group.”

Now — on the heels of news the IRS’s apology for having targeted conservative groups — NOM is renewing their demand that the Internal Revenue Service reveal the identity of the people responsible.

“There is little question that one or more employees at the IRS stole our confidential tax return and leaked it to our political enemies, in violation of federal law,” said NOM’s president Brian Brow, in a prepared statement. “The only questions are who did it, and whether there was any knowledge or coordination between people in the White House, the Obama reelection campaign and the Human Rights Campaign. We and the American people deserve answers.”
