The California Supreme Court on Thursday unanimously ruled against a law requiring presidential and gubernatorial candidates to disclose their past five years of tax returns for a spot on the state's primary ballot, per the Sacramento Bee.

Why it matters: California Gov. Gavin Newsom signed the bill in July in an effort to compel Trump to release his tax returns. While campaigning in 2016, Trump argued he could not release the records because he was under audit. The chairwoman of the California Republican Party sued over the law, sending the matter to the state's high court.

Between the lines: Ten states had similar bills working their way through the legislative process as of July, with requirements ranging from one to 10 years of prior tax returns for a spot on the ballot. It is not yet clear how California's ruling could reverberate throughout these other jurisdictions.

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
