INDIANAPOLIS (AP) – Indiana’s Senate Democratic leader says an investigation is needed after fundraising lists for former state schools chief Tony Bennett were discovered on state computers.

Senate Minority Leader Tim Lanane (LAN’-in) said Thursday that more information is needed about the discovery of the campaign materials. Indiana Inspector General David Thomas has confirmed his office is investigating Bennett but hasn’t described the nature of the probe.

The Associated Press reported Wednesday that three Republican fundraising lists and a donor call list for Bennett had been found on state hard drives. Bennett also sent an email from his state account directing staff to dissect a campaign appearance by Democratic opponent Glenda Ritz.

Both could violate Indiana election and ethics laws. Bennett denies any violations.

Ritz defeated Bennett in November.
