President-elect Barack Obama said he will release in a matter of days the results of an internal investigation into what conversations his aides and advisers may have had with embattled Illinois Gov. Rod Blagojevich. The internal probe, which aides described as thorough, is looking to root out every contact between Obama's camp and Blagojevich's camp, according to Obama's representatives. There was no clear timeline for the self-investigation to end, although Obama told reporters Thursday he would make the results public during "the next few days." Blagojevich was arrested Tuesday on charges that he put Obama's vacant US Senate seat up for bidding. The governor has ignored repeated calls for his resignation, including another one by Obama on Thursday, and retains the power to appoint Obama's replacement.
