Sacramento, California - Reparations advocates in California are demanding Governor Gavin Newsom take action as a deadline approaches to sign a bill requiring some companies to disclose their historic ties to chattel enslavement.

The Alliance for Reparations, Reconciliation, and Truth said on Instagram that it had delivered thousands of petitions to Newsom's office on Monday calling for the governor to sign AB 2599 into law.

Also known as the Truth in Disclosure Act, the legislation would require major corporations and contractors seeking to do business with the state to submit affidavits, under penalty of perjury, disclosing any past ties to enslavement. It applies to companies that were in existence, or whose predecessors were in existence, on or before December 31, 1964, and that have annual worldwide gross receipts exceeding $100 million.

The bill passed out of the state legislature last month. If signed into law, it would necessitate the creation of a public, digital platform for the records and affidavits.

An online campaign shows that at the time of writing, more than 3,600 letters were sent to the governor in support of the measure.

Newsom faces a September 30 deadline to sign the bill.

"We're not asking for a task force to go on tour," community organizer Toni McNeil said in a recent rally in support of AB 2599. "We're asking for truth, and we're asking for disclosure. And we're asking to show the receipts."
