SPRINGFIELD, Ill. — An Illinois legislative impeachment panel started work on an unprecedented impeachment process Tuesday, taking the first steps toward removing Gov. Rod Blagojevich from office.

The embattled Democrat signaled he isn't going down without a fight.

Lawmakers on Monday quickly shelved the idea of setting a special election where voters would fill the vacant Senate seat of President-elect Barack Obama — the seat the governor is accused of trying to sell before his arrest last week on federal corruption charges.

But the House also voted 113-0 to create a bipartisan committee that will recommend whether Blagojevich should be impeached.

Committee chairwoman Rep. Barbara Flynn Currie, D-Chicago, began the meeting by saying the Blagojevich scandal had created a "crisis of confidence" in state government. But she cautioned panel members against moving too fast.

"Let us remember that we're not Alice in Wonderland. We're not the Red Queen. We do not sentence first and then do the verdict," she said.

"Frontier justice will not prevail in this proceeding. A rush to judgment does not serve the people of the state well."

The House committee will eventually make a recommendation on whether to impeach to the full House, which would then decide whether to file charges against the governor. Then the Senate would hold hearings and ultimately make a ruling.

If the 21-member panel recommends impeachment, it would be the state's first such move against a sitting governor.

One major unanswered question is whether Blagojevich or his representatives will take part in the committee's work or simply ignore the proceedings. Blagojevich ignored reporters' questions as he left his Chicago residence before 9 a.m. Tuesday, carrying a briefcase and gym bag.

His legal woes were expected to grow as sentencing for convicted political fundraiser Antoin "Tony" Rezko was postponed indefinitely Tuesday. Court-watchers say the delay will give Rezko more time to talk to prosecutors about Blagojevich or other lawmakers.

Rezko, who raised more than $1 million for Blagojevich's campaign fund, was convicted of shaking down businesses seeking state business for campaign contributions. Witnesses at his trial testified that Blagojevich was aware of some of the incidents.

Senate Democrats on Monday dropped any discussion of a special election to fill Obama's Senate seat, for now leaving any decision about it in Blagojevich's hands.

Blagojevich, who has ignored strident calls to resign from Obama and virtually every lawmaker in the state, defiantly signed 11 bills into law Monday — including one mentioned in the 76-page FBI complaint against him. And he hired a bulldog defense attorney, Ed Genson, with a history of taking tough cases to trial.

Genson said Blagojevich would not step down. "He hasn't done anything wrong," the attorney said Monday night.

Meanwhile, Obama's team said an internal review showed that Obama's staff "was not involved in inappropriate discussions" with Blagojevich over the Senate seat. Obama said at a Chicago news conference that details of the review were being withheld at the request of prosecutors so more interviews could be conducted.

Controversy has swirled around Obama and his incoming White House chief of staff, Rep. Rahm Emanuel, following Blagojevich's arrest. Critics want to know whether Emanuel had spoken with aides to the governor about the seat. Obama said the results of the investigation by his incoming White House counsel would be released "in due course."

At the Capitol on Monday, House Speaker Michael Madigan — a Chicago Democrat and former co-chairman of Blagojevich's re-election campaign who has become one of the governor's fiercest critics — said the committee's review will include the criminal charges against Blagojevich as well as a long list of other possible wrongdoing during his six years in office: abuse of power, taking action without legal authority, ignoring state laws and defying lawful requests for information from the General Assembly.

The committee may well work through the holidays, but it's not clear how long it will take to produce a recommendation. That depends partly on whether the governor's legal team takes part by questioning witnesses and presenting evidence, which would significantly lengthen the process.

Blagojevich spokesman Lucio Guerrero said he didn't know how Blagojevich will respond to the committee.

The state constitution gives lawmakers broad authority to impeach a governor. The House would decide whether to file charges against the governor, and the Senate would ultimately rule on them.

Madigan was careful not to call for Blagojevich's resignation or say whether he thinks the governor should be impeached. Madigan said he would preside over any impeachment debate and so should stay neutral.

Madigan's daughter, Lisa, is the Illinois attorney general and widely seen as a top Democratic candidate for governor in 2010.

Madigan often has clashed with Blagojevich and said his staff has been studying impeachment for a year. His office produced a memo this summer outlining all the arguments legislative candidates could make in favor of impeachment.
