Questions Emerge About Who Knew What and When Regarding the Millenium Tower's Sinking

San Francisco Supervisor Aaron Peskin is angry about the role that an obscure state sanctioned agency – the Transbay Joint Powers Authority – had in keeping the Millennium Tower’s sinking problem from the public. NBC Bay Area has obtained a signed confidentiality agreement between the Transbay authority and Millennium Partners, the firm behind the project. It was a deal inked at a meeting back in 2010, long before the sinking problem became public. Investigative reporter Jaxon Van Derbeken reports.
