Lawyer Moms of America and Project Corazon (L4GG Foundation) have formed a travel bank to help reunite families and to support lawyers going to the border to do pro bono work. Since July 2018, they have received and used more than 1.2 miles and $12,000 to provide more than 75 flights to families in need and to attorneys traveling to the border.
