Without looking the Republicans and Kay Hutchinson pulled the funding for the double fence.
President George W Bush also fought the wall and dragged his feet building it. Note he and the Repulican leadership did nothing to stop Hutchison’s amendment.
Interesting a GOP Senartor from a “conservative” border state took the lead in killing the fence. I don’t recall Texas Governor Rick Perry raising his voice at the time. More evidence there is really little difference between the parties.
They ran out of barbed wire.
