The term "dark money" has been used a lot lately, especially during the current election season. How many individuals and organizations are giving money to certain candidates, causes or independent expenditure groups to help determine who wins certain offices? And should the public know who is behind the contributions?

Chris Herstam, former legislative leader, joined us to explain his opposition to "dark money."
