INDIANAPOLIS (AP) — Democratic Indiana schools Superintendent Glenda Ritz, who has said she’s considering a run for governor, is expected to make a campaign announcement this week.

Ritz’s campaign Facebook page posted a series of messages Sunday saying she would make a “special campaign announcement” Thursday at Ben Davis High School in Indianapolis. The posts didn’t give any further details. Announcements also were planned for Terre Haute and Evansville later Thursday and in Fort Wayne, South Bend and Hammond on Friday, according to the page.

Ritz earlier this year said she was considering running for governor. She couldn’t immediately be reached for comment Sunday.

She would join a Democratic field that already includes former Indiana House Speaker and 2012 nominee John Gregg and state Sen. Karen Tallian of Portage.
