Federal agents sought items related to at least 70 separate people or entities when they raided the office of state Sen. Martin Sandoval late last month, according to an unredacted search warrant released by the Illinois Senate on Friday.
Sandoval resigned from his position as chair of the Senate Transportation Committee Friday following the release of the warrant, according to a spokesman for Senate President John Cullerton.
On Sept. 24, agents executed search warrants at multiple locations tied to Sandoval, including his district office in Cicero as well as his office at the Illinois State Capitol. The warrant released Friday pertained solely to his Capitol office in Springfield.
Authorities sought items "related to any official action taken in exchange for a benefit" as well as information on "any business owned or controlled by" Sandoval, the warrant reads.
Agents also sought items related to ComEd and Exelon or any employee of those businesses - particularly four specific, unnamed representatives referred to simply as "Exelon Official" A, B, C and D.
The warrant also authorized agents to seize anything related to five officials with the Illinois Department of Transportation, also named only as "Official" A, B, D, E and F.
Agents sought additional materials in connection with Cook County Commissioner and McCook Mayor Jeff Tobolski, whose office was subsequently raided two days after Sandoval's.
Berwyn alderman and architect Cesar Santoy - who was appointed by Gov. J.B. Pritzker to the Illinois Toll Highway Authority Board of Directors earlier this year - was also named in the warrant, along with his construction firm.
Named in the warrant as well was Rick Heidner and his company Gold Rush Gaming, a video gambling operator with dozens of locations across the Chicago area and Illinois, and red light camera company SafeSpeed.
Also included in the document release was a two-page receipt for property showing items seized, including three computers computers, an iPad, five iPhones, seven USB drives, shredded paper and more.
No criminal charges have been filed against Sandoval, who did not immediately respond to request for comment. He has been in office since 2003 and is a member of the Senate Democratic Caucus leadership.
The raids at Sandoval's offices were one such effort in a long string of FBI searches at various locations tied to state and local political figures.
