Hi there.

Welcome to Meet the Press.

Now I'm Ryan Nobles in Washington, where President Trump just returned to the White House

after his five-day visit to Asia, which ended with a meeting with President Xi,

as the Trump administration looks to ease trade tensions with Beijing.

But it's President Trump's announcement just before those high-stakes negotiations that's

sending shockwaves, with President Trump ordering the Pentagon to start testing nuclear weapons.

The president posting on truth social while citing other countries' nuclear weapons

testing programs, writing, quote, I've instructed the Department of War to start testing

our nuclear weapons on an equal basis.

That process will begin immediately.

Later, while speaking to reporters on Air Force One, President Trump doubled down on his desire for the U.S. to resume nuclear testing.

About what was the nuclear testing? What prompted you to do that right before the meeting?

Well, that had nothing to do with them. It had to do with others. They seem to all be nuclear testing.

We have more nuclear weapons than anybody. We don't do testing. We've halted it years, many years ago.

But with others doing testing, I think it's appropriate that we do also.

It's really good.

It deals around the testing, sir, like where or when?

It'll be announced.

You know, we have test sites.

It'll be announced.
