The Tennessee General Assembly recently passed a bill requiring 501(c)(4) organizations – often referred to as “dark money” groups – to disclose any expenses over $5,000 in the 60 days leading up to an election. Previously, these groups could run advertisements featuring candidate names and likenesses without being required to disclose spending, so long as they did not expressly advocate for or against a candidate. Now, doing so will trigger disclosure for any spending over the $5,000 threshold.

Independent Neighborhood Action, a political action committee formed to “support the election of labor-endorsed candidates,” is sending out mailers in a last-minute push before the May 17 primary.
