U.S. Sen. Roland Burris says he never participated in a pay-to-play scheme despite the release of a transcript in which he offers to "personally do something" for then-Gov. Rod Blagojevich's campaign fund.

Burris spoke to reporters outside his Chicago home Wednesday before leaving on a two-day tour of central Illinois. The Democrat says he didn't try to buy President Barack Obama's vacant Senate seat and never committed perjury.

The senator's comments come one day after a judge allowed the release of a Nov. 13 wiretapped conversation between Burris and the former governor's brother. In it, Burris presses Robert Blagojevich for appointment to the Senate seat.

Burris on Wednesday said the transcript shows he's been truthful.
