Governor Dannel Malloy vetoed House Bill 5556 today, June 15, 2012. The campaign finance bill would have required corporate board authorization for campaign-related expenditures of $4,000 or more and disclosure of donor identities for donations aggregating $1,000 or more.

The bill was opposed by the Connecticut Business and Industry Association, the American Civil Liberties Union, and the Connecticut Daily Newspaper Association, who argued that the bill would have a chilling effect on contributions.

The bill did not pass with a two-thirds vote, making a veto override unlikely.
