HARRISBURG, Pa. -

The investigation of alleged finance violations by Vaughn Spencer's 2011 campaign for Reading mayor is ongoing, a spokeswoman for Pennsylvania Attorney General Kathleen Kane said Tuesday.

Carolyn Myers declined to comment any further on the case.

Kane's office took over the investigation after the Berks County Board of Elections released last November a report that alleged Spencer's campaign violated state code by making illegal contributions.

The elections board's investigation lasted 15 months, with the final report including testimony from Spencer and three members of his campaign.

At the center of the investigation is the largest donation Spencer's campaign received during the 2011 campaign -- $30,000 from the International Brotherhood of Electrical Workers union just four days before the election.

The same day Spencer accepted the check, according to the report, the then-candidate cut two checks for $10,000 each for the Philadelphia City Council campaigns of Bill Rubin and William Green.

The report alleges the $30,000 was given to Spencer to enable the union to funnel additional contributions to Rubin and Green, in violation of the Philadelphia Ethics Act.

Spencer's then-campaign manager, Michael Fleck of Allentown-based Fleck Consulting, released a statement in November, saying, "We follow all campaign finance laws, we believe. And, we ran an effective campaign for the mayor."

The elections board's report was also forwarded to the Philadelphia Ethics Board.
