Burris filed an affidavit with the Illinois House committee that oversaw Governor Blagojevich's impeachment, dated February 4, to supplement his earlier answer to a question posed by the committee. Burris acknowledged Rod Blagojevich requested "assistance in fund-raising" for the governor three times in the weeks and months before Blagojevich appointed Burris. Illinois House Republicans consider this to be at odds with Burris's testimony during the impeachment trial, and said they were considering pursuing a perjury investigation. Democratic officials, including Illinois Attorney General Lisa Madigan, supported an investigation. Burris stated that he told the governor's brother 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" and that he "did not raise or donate any funds to Governor Blagojevich after the fundraiser on June 27, 2008."
