A group of women from the Bronx and Westchester banded together to deliver aid to migrants in Mexico.

Marti Michael, a retired social services worker, has been going to the U.S.—Mexico border for a year to provide support.

On her most recent trip, her and 13 colleagues brought wagons of hot meals over the border to feed thousands of hungry migrants and their children living in an encampment in Matamoros.

Under the President Trump’s administration's "remain in Mexico" policy, asylum seekers have to wait in Mexico while their cases unfold in U.S. immigration court.

"They need everything, these people who are stuck in Mexico, most of them have walked from Latin America and gotten this far...during their walk, they've used up whatever supplies they had, they've been robbed and worse,” says Michael.

The United Nations Children's Fund reported 700 children are among the people stranded in the border city. They say that some children have been there for weeks and even months.

"We were in tears a lot of the time I have to say...thinking about those children I would tear up right now...but I would go back,” says Emita Hill, who was among the women who helped raise more than $18,000 to buy clothing, food and toys for the children.

In the United States, these women are just friends. But over in Mexico, they are heroes to the people they serve.

"You meet the people, and talk to them and hear their stories and love their children, now I can't not do it, I must go," Michael says.
