You're listening to the 1A podcast. I'm Todd's Williken for Jen White, and this is in case you missed it, where we bring you some of the week's most important conversations that you might have missed.

I think it's the most important decision, one of the most important decisions in the history of our country, because without tariffs, without our being able to use tariffs freely openly

and in every way, we are really, would suffer tremendously from a national security standpoint.

One of the most important decisions in the history of our country, says the President of the United

States. He's talking about tariffs, and tariffs get their day in court. On Wednesday,

the Supreme Court will hear arguments on two cases about the legality of President Trump's favorite

policy tool.

Now, shortly after he took office, Trump started signing executive orders, imposing tariffs on America's trading partners, even its friends.

He declared April 2nd Liberation Day and enacted a broad package of import duties from Canada to China and way beyond, upending the U.S. economy and reshaping global trade. He did it all without any input from Congress, and that might or might not have violated

presidential power under the Constitution. So are the Trump administration's tariffs legal?

Kate Shaw joins us after a break to help us understand the

arguments for and against and what's at stake. She's a constitutional law professor and scholar

at Penn Carey Law at the University of Pennsylvania and co-host of the strict scrutiny podcast.

Stay with us. We've got a lot to get into.

Thanks for having me back, Todd. So help us understand the basics. I said there are two cases.

Can you briefly explain the basics of these cases and how they combine into one big question of tariffs?
