In the panel's draft report released Thursday morning, state lawmakers investigating the governor concluded, "The Special Investigative Committee for the Illinois House of Representatives, 95th General Assembly finds that the totality of the evidence warrants the impeachment of the governor for cause.
"The committee, therefore, recommends that the House consider an Article of Impeachment against the governor."
The governor's office Thursday night called the panel's vote "a foregone conclusion" that was "flawed, biased and did not follow the rules of law."
On Friday, the Illinois Supreme Court also made a decision in the complex legal efforts to fill Obama's former Senate seat, ruling that Illinois Secretary of State Jesse White is not required by law to sign a certificate certifying Blagojevich's appointment to the position.
The drama surrounding Blagojevich escalated when he tapped former Illinois Attorney General Roland Burris to fill the seat just after Christmas, in the midst of the scandal.
Burris was denied the right to be seated in the Senate Tuesday because Democrats said he lacked White's signature on his appointment certificate.
With its decision Friday, the state Supreme Court put the onus back on the Senate to decide whether to seat Burris.
"Today the Illinois Supreme Court ruled that the secretary of state's signature is not needed to validate my appointment to the U.S. Senate by the governor," Burris said today in a statement. "I am very happy that the Supreme Court ruled supporting our argument that everything surrounding this appointment was legal and complete."
He added, "I am confident I have cooperated with all the requests of the U.S. Senate, and I expect they will validate my credentials and seat me in a timely manner."
White, along with Madigan, had made the argument in writing to the state Supreme Court that White's signature was not required by law but only recommended by a Senate rule.
"The secretary has performed all of his legal duties and the ultimate determination whether to seat petitioner Burris lies with the U.S. Senate," the filing stated. "That, too, is where the petitioners' remedy lies."
"It is clear that Secretary White is not the roadblock to Mr. Burris' appointment to the U.S. Senate," Madigan said in a Friday statement. "It remains within the power of the U.S. Senate to seat Mr. Burris. They should do so immediately."
Election law attorneys have said that senators may not have the constitutional power to refuse to admit Burris into the Senate without some indication that his appointment was corrupt.
Despite being denied entry to the Senate floor Tuesday, on Wednesday Burris saw his prospects looking up after meeting with Senate Democratic leaders.
"Roland Burris to me appears to be candid and forthright. ... He is not trying to avoid any responsibility or hide anything. ... We don't have a problem with him as an individual," said Senate Majority Leader Harry Reid, D-Nev. "[But] we want to do what we can do to make sure that everything that has been done in the Blagojevich hours is transparent."
A Democratic source also told ABC News that Obama talked to Reid about Burris Monday and urged him to come to "an amicable resolution" with Burris.
On Thursday, Burris also told state lawmakers investigating the possible impeachment that he did not act unethically in being appointed to the seat.
