Read between the lines:
After being told by prosecutors that their testimony could jeopardize the ongoing criminal investigation, the Illinois House panel considering impeachment charges against Gov. Rod Blagojevich will not subpoena advisers to President-elect Barack Obama, the panel's chairwoman said Sunday.
But U.S. Attorney Patrick Fitzgerald advised the state impeachment panel that testimony from Obama aides could jeopardize the criminal probe, Illinois Rep. Barbara Flynn Currie told CNN Radio.
The internal report, drafted by Greg Craig, Obama's choice for White House counsel, concluded that neither Obama nor his aides had any "inappropriate" contact with Blagojevich or Blagojevich's staff.
We could get more corrupt, but it's impossible. First, offer the guy who's going to write the report a position; he's not going to down his new boss. Next, testify in exchange for immunity, and so protect you and your own staff from implication. A great way to catapult forward on the shoulders of your equally corrupt benefactors.
