Gov. Greg Abbott isn't taking "no" for an answer when it comes to buoys placed in the Rio Grande to prevent illegal crossings. Speaking on Fox News Sunday Morning Futures, Abbott says an appeals court used an outdated law when it upheld a ruling ordering Abbott to remove buoys from the water. Abbott said the law applies to "navigable" waters and claimed the Rio Grande is not navigable "by definition." The governor said the state will file another appeal and if they lose that, they'll bring the case before the U.S. Supreme Court.
