Nick Reisman reports at New York State of Politics that a mysterious group calling itself American Opportunity is backing Gov. Kathy Hochul proposed $227 billion budget plan with TV and digital ads and mailers. But the group does not have to reveal its identity or who is providing the money until this summer, because of the tax code for a 501(c)(4) non-profit group. No one from the group would go on the record and identify the source of the funding, saying only, "American Opportunity is a 501(c)(4) established to promote social welfare and policies, and it has registered in New York state as a grassroots lobbying entity.... Our report in July will disclose contributions, as required by state law." Hochul and the legislature need to pass a budget by April 1. Read more about this story at New York State of Politics.
