As part of the ongoing investigation into charges that Gov. Rod Blagojevich and his chief of staff tried to get member's of the Chicago Tribune's editorial board fired, federal authorities have subpoenaed documents from the company.
The Tribune Co. made the announcement on its ChicagoBreakingNews.com Web site.
"As we've said before, we will fully cooperate with the government in its investigation into Gov. Blagojevich and his administration," Tribune spokesman Gary Weitman is quoted on the site as saying.
Federal authorities have alleged that Blagojevich -- angry over less-than-flattering editorials -- threatened to withhold state money for Wrigley Field renovations unless members of the newspaper's editorial board were fired.
Wiretap transcripts allege that Blagojevich instructed his chief of staff, John Harris, to pressure the company, which owns the newspaper and the ballpark.
Sam Zell, chairman of Tribune Co., acknowledged in an interview Wednesday on CNBC that the FBI had contacted him. [Video]
