They would have to report each contribution received of $100 or more, including the contributor's name, address and employer. Most information would be posted publicly on the attorney general's website.

According to the attorney general's office, 501(c)(4) social welfare organizations, exempt from federal and state taxes, have become major vehicles for political activity, including funding sham issue ads that attack candidates. They are "attractive conduits" because they can raise and spend unlimited money while concealing who supplies the money, the office said.
