From the New York Times, I'm Michael Barbaro. This is the deal.

Today, a caravan of Central American migrants is moving north through Mexico, headed for the U.S. border.

Why the Republicans won't stop talking about it and the Democrats are trying not to.

It's Wednesday, October 24.

Hello? Hey, Annie. Hello? Can you hear me?

I can hear you. Yeah. Yes. Are you a micro city? No, I was in Mexico City for a conference over the weekend.

And then I decided to come down to join this caravan as it makes its way north. Did you get there today?

I arrived a couple of hours ago. I left Mexico City this morning, flew into Tapatula, and we got a van and a driver.

Kind of a beat up blue minivan with non-working tours.

And what's your plan then? Well, actually, can I, I think I should try to find the van.

And so I don't get left behind here on the highway, but I'm happy to talk again.

Okay. I'll just send you audio that I'm getting from the road.

Okay. But I'll talk to you soon. That sounds good. Sounds very good. Thank you, Claire. Thank you, Annie.

So my name is Annie Corial. I'm a reporter based in New York. I'm in Chiapas in southern Mexico now following the migrant caravan.

As it makes its way north to the US border.

This is sort of the tail end of the caravan because thousands of people have been heading along this route all day.

So you can see evidence of that on the highway. There are orange fields and napkins and empty bottles of water.

They're ambulances that are, and there's a Mexican Red Cross van that's going along side with the migrants as they travel.

They've sort of brought traffic to a standstill. And almost every car and traffic is filled with it doesn't people.

It's really hot. The sun is just beating down. It was supposed to rain today, but there doesn't seem to be a cloud in the sky.

Behind me there's a man who is carrying a large white flag. He says, you know, it's a message that they come in peace.

And the news today is that there's another group that's sort of trying to join this caravan as it makes its way north.
