The US Supreme Court will hear arguments Wednesday on whether a wide swath of Donald Trump's tariffs are lawful, in a landmark case that could uphold -- or upend --

The US Supreme Court let the Trump administration, for now, withhold $4 billion in food aid that a judge had ordered distributed Friday to fully fund November benefits for 42 million people.

The order blocked the administration's prior plan to only partially fund benefits during the ongoing federal government shutdown.
