Gov. Gavin Newsom has already signed off on the most controversial part of Assembly Bill 1608, but he is now threatening to block the rest of the measure that would give California's high-speed rail inspector general more tools. The split decision leaves Ben Belnap with only part of the authority he says he needs to do the job he was appointed to perform.
The search around California High-Speed Rail is back because the bill is in the final stretch and could still be changed or vetoed, with the fate of the remaining oversight provisions hanging over the last two weeks of session. Assembly Bill 1608, authored by Assemblymember Lori Wilson, cleared the Senate Appropriations Committee last week and was two floor votes away from passing as written before the governor moved on part of it through a state budget trailer bill.
The provisions Newsom already enacted give Belnap new authority to temporarily withhold portions of reports that would expose security risks, fraud-detection gaps or pending litigation. Critics called those changes anti-transparency. Belnap, whose office was created in 2023 with the power to audit contracts, investigate fraud and flag problems, says the rest of the bill is still needed because the state has never fully given him the tools to carry out that mandate. He has described those powers as absolutely essential.
The remaining sections would go further. They would give the inspector general purchase authority and job classifications, two things that can determine whether an office can hire, equip and manage staff on its own or must rely on someone else to do it for him. That matters because the watchdog was created to stand apart from the project it oversees, and the point of Assembly Bill 1608 was to expand that independence rather than leave it dependent on others for basic administrative functions.
That is where the fight sharpens. The governor's office said, We don't typically comment on pending legislation, while Wilson's office said there has been no direct language about amendments nor a possible veto. But the fact remains that Newsom has already enacted the transparency-related sections while appearing ready to veto the rest, a move that would preserve the new limits on reporting but deny the inspector general the broader tools he says are essential.
The stakes are bigger than one bill. California has been trying to build the nation's first bullet train for years, and the project has long been described as ballooning in cost and missing deadlines. CBS California Investigates recently reported that it could run out of money as soon as 2027 without new financing. Trailer bills move quickly with the budget and face less public vetting than standalone measures, so the final version of Assembly Bill 1608 could still change before the session ends. If Newsom follows through, Belnap will be left with a watchdog office that can warn about problems but may still lack the authority he says would let him fully police the project.
