The migrant caravan approaching the U.S. has split into several groups.
At least 3,000 migrants from the original caravan have applied for asylum in Mexico, while hundreds more have reportedly returned home, according to Mexican authorities.
Around 4,000 migrants are still en route to the U.S. and are expected to pass through Veracruz in the next few days.
This as the president said he is prepared to send as many as 15,000 troops to secure the southern border.
