Public scrutiny joining research claims, commercial safeguards and certification
The February 2025 Blackburn–Blumenthal advertising inquiry consists of letters seeking information about ad placement, verification and industry certification following Adalytics research. The senators requested responses by 14 February from DoubleVerify and relevant accreditation bodies.
The Senate office says the senators received Adalytics research before publication. Their DoubleVerify letter asks about remediation, advertiser notification, NCMEC information, authority reports and related revenue. Letters to the Media Rating Council and TAG ask about audits, fee policies and review or revocation. Check My Ads credits its advocacy with helping the inquiry, but the Senate documents do not establish its drafting role. These are documented requests, without a subpoena, violation finding or observed sanction.
