Washington, D.C. (ABC) -- Among the voices calling for Blagojevich to step down, President-elect Barack Obama is facing mounting pressures of his own.
Republican officials are calling on him to answer tough questions about what role his team may have played in the scandal.
Senior White House correspondent Jake Tapper is in Washington with more.
Law enforcement officials tell ABC news that "senate candidate #5" in the criminal complaint against Governor Blagojevich is a close ally of President-elect Obama's -- democratic congressman Jesse Jackson Jr.
In the complaint, Blagojevich tells an aide that an emissary for candidate 5, promised "he'd raise me 500 grand, then the other guy would raise a million if I made him senator"
Jackson says nothing could be further from the truth, and he hasn't been charged with anything
He said, "it is impossible for someone on my behalf to have a conversation that would suggest any type of quid pro quo or any payments or offers."
The president-elect has remained mostly out of sight but through a spokesman sent a clear message to the governor: resign.
When the story first broke, Mr. Obama was far more circumspect.
Obama said, "I had no contact with the governor or his office 4 and so we were not--I was not aware of what was happening. And as I said, it's a sad day for Illinois. Beyond that I don't think it's appropriate to comment."
But how long can Obama avoid comment?
The criminal complaint suggests that the governor was angry that his offer to Obama's team -- make me a cabinet secretary and I will name your favorite candidate to replace you -- was rejected.
But who rejected it?
Republican Party officials are now calling for the president-elect to disclose all communications between his team and the governor's, one saying Obama's promise of transparency to the American people is now being tested.
Some Democrats seem to agree.
