New details are emerging in the scandal surrounding the Internal Revenue Service's targeting of conservative groups.

The IRS has reportedly found 6,400 new emails that belonged to former official Lois Lerner, who oversaw the tax agency’s Exempt Organizations Unit.

Gerri Willis reported on "Happening Now" that the IRS has said it will not hand over the emails until it can make sure there are no repeats.

She noted that Judicial Watch has been seeking the emails as part of a Freedom of Information Act request filed two years ago.

"The tax agency has been mired in scandal over its denial of special tax status to conservative groups, especially Tea Party groups," Willis noted.

"A U.S. district court called for the IRS to address the status of the emails by June 12th, but now the IRS legal representatives are saying that checking for copies among the 6,400 emails will delay their analysis past September," Willis said.

"If it's not one thing, it's another."
