You do know the story, don't you? After Blago appointed him to fill Obama's Senate seat Burris was called back to Illinois to testify before a state Senate committee looking into Blago's corruption. While under oath Burris said that he had not had discussed making any payments to Blago with any of Blago's staff, including his brother. Then Burris discovers that the feds have a tape of him discussing a campaign donation with Blago's brother. Don't you just hate it when that happens? So ... time for a little CYA. Burris suddenly wants to submit an affidavit to the Illinois senate expanding his testimony. Since they have him on tape he had better fess up and tell them that he talked to Blago's bro about some money.
This is called perjury. We learned while Bill Clinton was president that only Republicans like Scooter Libby are punished for perjury. Democrats get a pass. Let's see if it works this way for Burris.
