On the program today, the quickly developing Trump economy, where and how to rebuild after wildfire, and then rocks.

Just a bunch of rocks.

From American public media, this is Marketplace.

In Los Angeles, I'm Kyle Rizzell.

It is Tuesday to date the 21st of January.

Good as always, to have you along, everybody.

The first of the changes that President Trump is going to be bringing to this economy were revealed last night. We're going to talk about energy later on in the program.

We're still waiting on his promised immigration crackdowns. That is a labor story, remember.

And the first slice of tariffs seems to be on track for February 1st. In the Oval Office last night, the president said he's

looking at 25% import taxes on Canada and Mexico, which are not for nothing. This country's

two biggest trading partners, countless categories of goods cross our mutual borders. But tariffs

would spell particular trouble for one very important industry that is spread across all three countries.

Marketplace's Supreme Beneshore starts us off.

We trade all kinds of things with Canada and Mexico.

Milk, timber, meat, minerals, but the biggest out of all of them is cars and their parts.

Technically, it's 100% assembled in the U.S.

But the Model 3 has 20% of its content from Mexico.
