Insider and several other news organizations have identified 69 members of Congress who’ve recently failed to properly report their financial trades as mandated by the Stop Trading on Congressional Knowledge Act of 2012, also known as the STOCK Act.

Congress passed the law a decade ago to combat insider trading and conflicts of interest among their own members and force lawmakers to be more transparent about their personal financial dealings. A key provision of the law mandates that lawmakers publicly — and quickly — disclose any stock trade made by themselves, a spouse, or a dependent child.

But many members of Congress have not fully complied with the law. They offer excuses including ignorance of the law, clerical errors, and mistakes by an accountant. Insider has chronicled this widespread nature of this phenomenon in “Conflicted Congress,” an ongoing reporting project initially published in December.
