Mike Frerichs' largest campaign donor (according to Capitol Fax) is State Senate President John Cullerton.
He's the same guy who's refusing to release any of the records from Mike Frerichs' tenure in the State Senate.
Coincidence? Not in Illinois. Not with Democrats.
From CapFax:
When operatives for Democratic state treasurer candidate Sen. Michael Frerichs sent Freedom on Information requests to the Illinois House Clerk for lots of files on his GOP opponent Rep. Tom Cross, the House complied. But Cross’ people have asked for most of the same documents from the majority Democratic Senate and have been denied.
...The Cross people are understandably upset about this, particularly since President Cullerton is Frerichs’ single largest donor this year.
