State Attorney General Tom Corbett said today he soon will make an announcement regarding a state grand jury's corruption investigation into the state Legislature.

We do have something coming up within a few days," Corbett told KYW/KDKA radio.

"We have something come up that's imminent that when people hear it they'll think it's Bonusgate but it's not," Corbett said. "That's about the only way I can put it."

Bonusgate refers to the first phase of Corbett's probe that resulted in the filing of criminal charges in July against 12 people with ties to the House Democratic Caucus. Many of the charges against former staffers and a former Democratic legislative leader were tied to allegations of using taxpayer-funded stipends to reward caucus employees who worked on campaigns or did political work.
