McALLEN — One morning in mid-November, Mario Guerrero, the executive director of the South Texas Builders Association, was checking a group chat when a video of federal agents detaining people from a construction site popped up.
He watched the video of Immigration and Customs Enforcement agents detaining workers who were pouring cement in front of a home in an idyllic neighborhood here in the Rio Grande Valley.
For nearly a year, Guerrero had seen similar videos or read news reports of arrests and raids. This was the last straw.
