CHICAGO (AP) — Sen. Roland Burris insisted Monday that a newly released affidavit outlining contacts with ousted Gov. Rod Blagojevich’s brother and other advisers was voluntary and not the result of contact from federal agents investigating the former governor. “It was done because we promised the [impeachment] committee we would supplement information in case we missed anything,” Burris said Monday before embarking on trip to talk with constituents. “End of story.” Burris released an affidavit over the weekend in which he admitted Blagojevich’s brother asked him for campaign fundraising help before Blagojevich appointed Burris to the Senate.——Contact the Daily Reveille’s news staff at [email protected]
