Garcia is now asking Hispanic women not to join the military. He said the military is not doing enough to protect enlisted women, and that needs to change.

Rodriguez teamed up with the organization FIEL to march alongside the Guillen family. This Saturday at 5 p.m., they will meet at Discovery Green and make their way to City Hall.
"You know, I have little sisters, little nieces. Some of them do want to join the military. When I see Vanessa, I see them," he said.
