Burris also reiterated that he did not commit perjury in previous testimony regarding his involvement in an alleged "pay-for-play" scheme to fill the Senate seat from Illinois vacated by President Obama.
The lawmaker's denials came one day after a federal judge approved sending recordings of the conversations, which took place before Burris' appointment, to the U.S. Senate Ethics Committee.
