As previously undisclosed subpoena adds another angle to federal agents’ activity surrounding the longtime House speaker and chairman of the Democratic Party of Illinois.

State Sen. Martin Sandoval has resigned as chairman of the powerful Illinois Senate Transportation Committee, weeks after federal authorities raided Sandoval’s home and offices as part of an ongoing corruption probe.

As the Sandoval scandal develops, Illinoisans should be careful not to confuse personnel changes for reform.

The lawmaker who carried to the governor’s desk an infrastructure plan that doubled the state’s gas tax used his influence as a powerful state lawmaker to land his son a government job, a lawsuit alleges.

The target, state Sen. Martin Sandoval, D-Chicago, is as clouted as they come.

A fourth political ally of Illinois House Speaker Mike Madigan has become the latest target of an ongoing federal investigation.

Chicago’s top FBI officer offered term limits as one solution to Chicago’s culture of corruption, suggesting more revelations are on their way, as he moves into an executive role in Washington, D.C.

Madigan has long been criticized for his control of a lucrative law firm specializing in Cook County property tax appeals.
