From Texas Standard:
House Bill 11, passed during the 2015 legislative session, is a sweeping law pitched as part of a broader $800 million border security effort. It expands the border presence of the Texas National Guard, green-lights hiring more troopers, and mandates an intelligence center to analyze crime data at the border.
One of the law’s other provisions has recently drawn a lawsuit that's just now making headlines. The Mexican American Legal Defense and Educational Fund, better known as MALDEF, has filed suit against Texas over what's called the “immigrant harboring” provision. They argue that it's unconstitutional under federal law.
