Governor Greg Abbott gave several GOP Governors a tour of the Texas border Monday afternoon. The tour comes on the eve of a federal court hearing involving a lawsuit challenging Texas’ authority to deploy nearly a thousand feet of buoys near the Camino Real bridge in Eagle Pass.

Texas began rolling out what is set to become a new floating barrier on the Rio Grande on Friday in the latest escalation of Republican Gov. Greg Abbott’s multibillion-dollar effort to secure the U.S. border with Mexico, which already has included bussing migrants to liberal states and authorizing the National Guard to make arrests.
