TORNILLO, Texas — Mayors from across the nation are in Texas taking a stand against the separation of immigrant children and their families.

While President Trump has signed an executive order, reversing his administration's policy that separates families who cross the border illegally, there's still no timeline or outline for how and when families will be reunited.

Austin's Mayor Steve Adler is among the city leaders speaking along the border near El Paso.

Adler says children should not be used to deter people from crossing the border and seeking asylum.

“This is about  children. There are over 2,300 children separated from their families. We don’t know when they're going to get unified. There are thousands of children that came to this country unaccompanied. Many if not most of them have families in this country. They should be with their families,” Adler said.

The mayors, on Thursday, were denied access to tent city of Tornillo where immigrant minors are being held.
