On Monday, the longtime Chicago Democrat was charged with bribery and tax offenses stemming from his support of the red-light camera industry when he served as the powerful head of the Senate Transportation Committee.
Sandoval, meanwhile, joins a growing list of Illinois politicians facing pending criminal charges.
Burke, the city’s longest-serving alderman and once the powerful head of the City Council Finance Committee, has pleaded not guilty to corruption charges.
Federal prosecutors have separately charged state Sen. Tom Cullerton, D-Villa Park, over an allegedly no-show union job, and former state Rep. Luis Arroyo, D-Chicago, who is accused of allegedly attempting to bribe a state senator to support gambling-related legislation.
Cullerton has pleaded not guilty and is awaiting trial. Arroyo is scheduled to appear for an arraignment next week.
State Sen. Terry Link, D-Vernon Hills, has been identified by a Tribune source as a cooperating witness against Arroyo, but he has adamantly denied it.
