SACRAMENTO, Calif. (CN) – California will become the first state to require presidential candidates to release their tax returns in order to land on the state’s primary ballot, under legislation signed Tuesday by Gov. Gavin Newsom.

Inspired by President Donald Trump’s refusal to release his returns during the 2016 campaign, the measure coined the “Presidential Tax Transparency and Accountability Act” forces candidates to reveal at least the last five years of their tax returns. The measure, which was vetoed in 2017 by former Gov. Jerry Brown, means California voters could have access to Trump’s tax returns in 2020.

In a signing statement, Newsom said California has the constitutional authority to set its own election rules and that Senate Bill 27 should “be a national standard.”

“As one of the largest economies in the world and home to one in nine Americans eligible to vote, California has a special responsibility to require this information of presidential and gubernatorial candidates,” the Democratic governor said. “The disclosure required by this bill will shed light on conflicts of interest, self-dealing, or influence from domestic and foreign business interest.”

Though the bill is meant to force Trump’s hand in the upcoming election, it will apply to Democratic candidates as well. It will also require future gubernatorial candidates to make their tax returns available to voters on Secretary of State’s website.

The bill’s Democratic authors say their main goal is to ensure that candidates aren’t running for office for personal profit.

“If he has nothing to hide, President Trump shouldn’t be afraid to give American voters what they want, a copy of his tax returns,” said state Sen. Mike McGuire, D-Healdsburg. “This commonsense legislation applies equally to all candidates, from all political parties, including the governor of California.”
