Public.Resource.Org has discovered that the Internal Revenue Service has posted the Social Security Numbers of tens of thousands of Americans on government web sites. The database in question contains the filings of Section 527 political organizations such as campaign committees. This Section 527 database is an essential tool used by journalists, watchdog groups, congressional staffers, and citizens. While the public posting of this database serves a vital public purpose (and this database must be restored as quickly as possible), the failure to remove individual Social Security Numbers is an extraordinarily reckless act.
On July 2, Public.Resource.Org discovered this systematic violation of Americans' privacy and notified the U.S. Treasury Inspector General for Tax Administration. We documented our findings in an audit document, copies of which were furnished to I.R.S. officials and senior White House officials. On July 3, the administration removed this database from public view.
