Democrat Ed Burke, Chicago’s longest-serving alderman, a longtime-ally of former Illinois House Speaker Michael Madigan and a towering figure in city politics, has been sentenced to prison time in the latest in a long history of high-profile corruption cases to rock Illinois.

Burke, who used his significant influence to steer business to his law firm in exchange for helping companies navigate the Chicago City Council, was convicted on 13 charges of bribery, racketeering, and extortion. He was sentenced to two years in prison and fined $2 million for leveraging his position to improperly influence business dealings for personal gain.

Senate Republicans cite this conviction as further evidence of the urgent need for tougher ethics reforms to hold politicians accountable and make it easier for law enforcement to investigate public corruption.

Senate Republicans have continued to fight the culture of corruption that has long tainted Illinois politics, pushing for greater accountability and transparency. Recent proposals from Republican lawmakers include stronger revolving door prohibitions, banning elected officials from working as paid lobbyists and campaign finance reforms.
