Gov. Bruce Rauner has signed Senate Bill 248, increasing the transparency of political spending. The bill requires political committees making independent expenditures of $1,000 or more file a report within five business of the expenditure.

If the expenditure is made during the 60-day period before an election, the report must be filed within two business days.

The bill, now Public Act 99-0437, goes into effect on January 1, 2016.
