Monday night the IRS confirmed that they posted around 100,000 Social Security numbers by mistake on a government website. The Social Security numbers were added to an IRS database called 527s, which is for tax-exempt political groups.

This giant mistake made by the IRS was discovered by a group based in California called Public.Resource.org, who said said the Social Security numbers were mostly those of donors, but some were from American’s who prepared tax returns to furnish to the IRS.

A spokesman for the IRS told Fox News they have removed web access to the information and are assessing the situation and exploring available options.

Public.Resource.org. founder Carl Malamud told Fox News, “It is time now for the administration to send a tiger team over to the IRS to help fix their information management practices.”
