SACRAMENTO — President Trump will be ineligible for California’s primary ballot next year unless he discloses his tax returns under a state law that took effect immediately Tuesday, an unprecedented mandate that is almost certain to spark a high-profile court fight and might encourage other states to adopt their own unconventional rules for presidential candidates.
The law, signed by Gov. Gavin Newsom on the final day he could take action after it passed on a strict party-line vote in the Legislature earlier this month, requires all presidential candidates to submit five years of income tax filings.
