Sen. Susan Collins violated the disclosure provisions of a federal financial transparency law she helped write by failing to properly disclose her husband’s purchase of a pharmaceutical company corporate bond, a NOTUS review of congressional financial disclosures indicates.

Collins’ husband, Thomas Daffron, purchased a Pfizer corporate bond worth from $15,001 to $50,000 on February 3, but Collins didn’t disclose the purchase to the Senate until Wednesday.

In an email to NOTUS, Collins’ office acknowledged the late disclosure, which is a violation of the Stop Trading on Congressional Knowledge Act, a law passed in 2012 that Collins championed.
