The government's opponents in the case argue that Trump exceeded the economic powers Congress granted to him under IEPA, the International Emergency Economic Powers Act.

The case clearly is top of mind for Trump, and he brings it up routinely in speeches and when talking to reporters.

Several justices, including conservatives, expressed skepticism at the government's arguments in the case.

If the court rules against Trump, it's possible his administration would use other laws to try to replace the overturned tariffs.

Some of Trump's ideas he has been able to enact himself, like pulling back tariffs he himself instituted on some foods and beverages.

Some he would need Congress to pass, like the outline of a health care plan he pitched, which would give Affordable Care Act subsidy money directly to consumers.

Speaker Mike Johnson has given a tepid response to another new Trump idea to cap credit card interest rates at 10%.

Trump has been putting more energy into the affordability message since Democrats won November elections by leaning into that topic.

However, his administration's attack on Venezuela, ICE troops in Minneapolis, and threats to Greenland have often overshadowed that message.

And you do have to wonder how President Trump would react were Congress to actually pass the extension on these enhanced ACA subsidies.

Because just a few days ago, Trump told reporters on board Air Force One that he didn't know if he would sign such a bill.

And the White House, in following up on that, had said that, well, Trump wants the money to go straight to people and not into Americans.

the subsidies for people on these health care exchanges.

This is a reference to Trump's great health care plan, which we are going to get into.

But you do have, as we've talked a lot about when we've talked about these extensions, a lot of people in red states, as Senator Murkowski and plenty of other senators know, who do depend on these subsidies, not just Democrats.

So Trump and any other Republican faces kind of a dilemma here.

Which way do you go?

Trump right now is really focused on the messaging that he has a health care plan.
