The Americans were stopped as they tried to bus 33 children across the border into the Dominican Republic, allegedly without proper documents.
The group's leader, Laura Silsby, says they had the best intentions and were hoping to save abandoned children from the chaos following the earthquake. The Baptist church members from Idaho say they planned to take 100 kids to a rented hotel in the Dominican Republic to establish an orphanage.
She says the group had documents from the Dominican government, but didn't seek paperwork from Haiti.
Sean Lankford, whose wife and daughter are being held, says consular officials from the U.S. Embassy in Haiti have met with the Americans to give them bug spray and food.
He says the group goes in front of a judge Monday.
