It’s not as big as the first, but a second caravan is now making it’s way through Mexico from Central America.
This one is just under a thousand people, not the seven-thousand or so in a caravan nearing the border.
Hundreds of migrants are seen wading across the river in Mexico.
They say they’re fleeing poverty and violence in their country.
The trek is thousands of miles on foot, but most say it’s worth it.
It could take this caravan a month or longer to reach the border.
The vast majority of the Central Americans asking for asylum in the U.S. have come through the Rio Grande Valley.
