Texas authorities added even more buoys into the Rio Grande on Wednesday to stop illegal crossing after the Biden administration unsuccessfully sued the state over its floating border barriers.

“Despite the Biden-Harris Administration’s attempts to shut down our border security efforts, the buoys are here to stay,” Republican Gov. Greg Abbott posted on X, along with a video showing a section of interconnected, washing machine-sized orbs, that spin when grabbed, being lowered into the water.

“We won’t back down from our mission to deter & repel illegal immigration,” he added.

Officials in border states are bracing for a possible surge of migrants to the border as illegal crossers rush to try to get into the US before President-elect Trump takes office.
