A conservative government watchdog says it has obtained emails revealing that the Internal Revenue Service sent conservative groups’ private tax exemption application and tax return information to the Federal Elections Commission, in violation of federal law.

According to Judicial Watch, the emails from Jan. 2009 to the present, provided by the FEC in response to an August 2013 Freedom of Information Act request, yielded a “revealing email chain” between former Internal Revenue Services (IRS) Director of Exempt Organizations Lois Lerner and enforcement attorneys at the Federal Election Commission (FEC).

Judicial Watch explains that in one email exchange beginning on Feb 2, 2009, an FEC attorney requests information about the American Future Fund’s (AFF) tax-exempt status from Lerner.
