Well I find it funny that prisons manage to build walls & fences that keep even the most determined inmates inside. Razor wire and electricity put an end to 35' ladders. Of course the politicians know this. The politicians instead of doing their duty focus on serving their own special interest meaning obeying corporate donors who want cheap illegal labor. That means they lack the will and in some cases their corruption is what keeps a fortified border wall from being built.
Either politicians must immediately fund and start construction on the entire wall NON STOP UNTIL COMPLETION and for our military being armed and placed on the border now or they stand against the Constitution of The United States and their oath of office that includes governors.
The Texas border is a river. Portions are virtually uninhabited on both sides.
