Turns out they also shared confidential information with ProPublica:
In response to a request for the applications for 67 different nonprofits last November, the Cincinnati office of the IRS sent ProPublica applications or documentation for 31 groups. Nine of those applications had not yet been approved—meaning they were not supposed to be made public. (We made six  of those  public, after redacting their financial information, deeming that they were newsworthy.)
On Friday, Lois Lerner, the head of the division on tax-exempt organizations, apologized  to Tea Party and other conservative groups because the IRS’ Cincinnati office had unfairly targeted them. Tea Party groups had complained  in early 2012 that they were being sent overly intrusive questionnaires in response to their applications.
That scrutiny appears to have gone beyond Tea Party groups to applicants saying they wanted to educate the public to “make America a better place to live” or that criticized how the country was being run, according to a draft audit cited by many outlets. The full audit, by the Treasury Department’s inspector general for tax administration, will reportedly be released this week. (ProPublica was not contacted by the inspector general’s office.)
Before the 2012 election, ProPublica devoted months to showing how dozens of social-welfare nonprofits had misled the IRS about their political activity on their applications and tax returns. Social-welfare nonprofits are allowed to spend money to influence elections, as long as their primary purpose is improving social welfare. Unlike super PACs and regular political action committees, they do not have to identify their donors.
You know how it takes forever to get something you have requested from the Government? Not in this case:
Just 13 days after ProPublica sent in its request, the IRS responded with the documents on 31 social welfare groups.
They sure wanted to get that information out in a hurry, didn't they?
This is what happens when the Press doesn't do its job, and the Executive Branch is allowed to do whatever it wants.
I'm sure things will be different when the IRS has a significant hand in your private health information.
