And so, for us, it was something that we thought could potentially happen, but it was certainly shocking to have it actually happen,” said Las Americas Executive Director Marisa Limon Garza.  FILE - Migrant parents socialize outside the Annunciation House, June 26, 2018, in El Paso, Texas.

And so, any kind of attack like this tries to undergird those efforts and destabilize them. That's an incredibly dangerous move and something that we felt like we needed to stand up against. And that's why we filed our own lawsuit,” Garza said.  KTSM reached out to Paxton’s office requesting for comment, which they did not immediately respond to Thursday afternoon.  The lawsuit argues this is just the latest attempt by Paxton to “target” and “harass” immigrant service organizations by making reference to four other instances where his office tried shutting down organizations like these in Texas, unsuccessfully.  Senior attorney with the Texas Civil Rights Project Aron Thorn, who along with law firm Winston & Strawn is representing Las Americas, noted however that Las Americas is the first of these organizations that specifically renders legal services.  “The significance of hitting a bunch of lawyers with these bogus attempts is it really does a disservice to your clients. It prevents you from being able to speak openly and with confidence with your clients about very difficult subjects. There is a reason that there is attorney-client privilege,” said Thorn.  The lawsuit was filed in the U.S. District Court in El Paso and is pending a request for an immediate hearing.
