CA State Police probing whether Bay Bridge critics were muzzled

'"I find myself in a difficult position," Transportation Secretary Brian Kelly told the members of the state Senate Transportation and Housing Committee, noting that some of the accusations against Caltrans and bridge project officials go back six years, well before he took his job in 2013.
Kelly said he had told the CHP to investigate whether bridge officials retaliated against engineers who criticized work on the $6.4 billion span and whether they violated the state Public Records Act in allegedly hiding evidence of problems.'
