Burris filed an affidavit with the Illinois House committee that oversaw Governor Blagojevich's impeachment, dated February 5, to supplement his earlier answer to a question posed by the committee.   Burris acknowledged Rob Blagojevich requested "assistance in fund-raising" for the governor three times in the weeks and months before Blagojevich appointed Burris. Burris said he told Rob Blagojevich that he could not donate to Gov. Blagojevich because "it could be viewed as an attempt to curry favor with him regarding his decision to appoint a successor to President Obama."  Burris stated that he neither donated to nor raised funds for Blagojevich after a fund-raiser on June 27, 2008.  Saying that this is at odds with Burris' testimony during the impeachment trial, Illinois House Republicans said they would consider pursuing a perjury investigation.  Democratic officials, including Illinois Attorney General Lisa Madigan , supported that announcement.
