A once-all-powerful Democratic politician in the deep blue state of Illinois is now facing the prospect of spending the remainder of his life behind bars in federal prison.

Former Illinois House Speaker Michael Madigan, 82, was found guilty on Wednesday by a jury on 10 of 23 federal corruption charges that had been pressed against him, Breitbart reported.

Madigan, who served in the state House for roughly five decades and held the powerful role of speaker for around 30 years, was also acquitted on seven of the 23 charges after nearly two weeks of jury deliberations, but the judge declared a mistrial on the remaining six charges after the jury became deadlocked on those counts.

Found guilty but also acquitted on some counts and deadlocked on others

According to a Justice Department press release, Madigan was found guilty on 10 federal counts that included four counts of using interstate facilities to promote unlawful activity, three counts of wire fraud, two counts of bribery, and one count of conspiracy to commit an offense against the U.S.

He was acquitted, however, on seven counts that included four additional counts of promoting unlawful activity through interstate facilities, two separate counts of bribery, and one count of attempted extortion.

The jury was deadlocked, and a mistrial was declared, for six more criminal charges for Madigan that included two more counts of wire fraud, another count of bribery, another promotion of unlawful activity charge, another conspiracy against the U.S. charge, and an overarching racketeering conspiracy count.

The DOJ release noted that for the charges he was convicted on, Madigan could face maximum sentences of 20 years each for the three wire fraud counts, 10 years each for the two bribery counts, and five years each for the rest of the counts, resulting in a grand total of up to 105 years in prison, if ordered to serve each sentence consecutively instead of concurrently.

Prosecutor says bribery "is still illegal"

Capital News Illinois reported that the acting U.S. Attorney for the Northern District of Illinois, Morris Pasqual, briefly spoke with reporters at the federal courthouse after the jury's verdict was rendered and revealed that no decision had been made yet on whether to pursue a new trial for the six counts on which the jury had been deadlocked and a mistrial had been declared.

Still, despite the mistrial on six counts and acquittal on seven counts, the federal prosecutor declared the 10-count conviction of Madigan to be a "win" in his view.

"Bribery -- whether it’s the old-fashioned cash stuffed in an envelope or the more refined version practiced by Madigan -- is still illegal, it’s still corrupt, and it’s still against the law, and it still undermines public confidence in government," Pasqual said. "Public officials [who] choose to violate the public trust can and should be held accountable."

Long history of actual and alleged criminality

Capital News provided a lengthy and detailed rundown on the near-decade-long criminal investigation into Madigan and several of his associates over allegations that he exploited his supremely powerful political position to provide various favors for others in exchange for bribes and other favors for himself and his friends in return.

The conviction, which adds Madigan to the state's pantheon of infamously corrupt public officials, completes the stunning fall from grace for the man who effectively controlled the entire state of Illinois, including exerting substantial influence over governors from either party, and dominated the state's Democratic Party for decades.

What ultimately did him in was a failed scheme involving a former Chicago alderman-turned-FBI-informant who desired an appointment to a lucrative state board position, as well as a bribery scheme involving no-work contracts for several of Madigan's associates with the Commonwealth Edison electric utility company.

The outlet noted that allegations of criminality and rumors of impending indictments had swirled around Madigan for years and ultimately compelled him to resign as speaker in 2021, followed a short time later by the resignation of his House seat and from his long-held role as chair of the Illinois Democratic Party.
