And finally, in California, the yes win for Proposition 50 will give California Democrats the chance to redraw their maps in time for the midterms as a response to recent gerrymandering efforts by Republican states.

But Governor Gavin Newsom's speech was sober in tone, a stark contrast to the celebrations elsewhere.

He called it an extraordinary night for his party, but there were no smiles or fist pumps as he addressed supporters.

Yesterday, Trump's press secretary, Caroline Leavitt, said the administration was looking into executive action after Trump made unsubstantiated claims of voter fraud in California.

California's agency in charge of elections described that claim as baseless.

Late into the night, Democratic strategists pored over the results in search of takeaways.

The party has spent the past year debating what lessons to take from a punishing 2024 defeat.

Today, for the first time in a while, the key question is how to understand their success.

Now to the Supreme Court, which today will consider whether President Trump had the legal authority to impose many of his sweeping global tariffs.

Their decision could define a central plank of Trump's agenda and send ripples through the global economy.

The Constitution grants Congress the power to impose tariffs.

But to get around that, Trump has relied on a decades-old Emergency Economic Powers Act.

As Bloomberg Supreme Court reporter George Storr told us, the case today rests on a key question.

Storr said that Trump's argument rests on two claims, that both the trade deficit and the flow of fentanyl into the U.S.

amount to emergencies that he should be able to address using tariffs.

If the Supreme Court disagrees, it's unclear how easily the White House could achieve their goals by other means, or if Trump has to completely unwind this crucial pillar of his economic agenda and geopolitical strategy.

They would also raise questions about the fate of tariff revenue that's been collected so far.

According to data collated by U.S.

Customs and Border Patrol, American businesses have paid the government almost $90 billion to cover the specific tariffs being challenged here.

Trump has acknowledged that a ruling against him would mean that refunds could potentially be issued.
