Efforts are underway in Crowley County to recall the sheriff, who was acquitted recently on charges stemming from a chemical spill during a drug raid.
However -- Sheriff Jeff Keyes is challenging a petition seeking a recall election.
County officials have approved a recall petition -- but Keyes says nearly 30 of the 342 signatures are questionable.
Recall organizers need at least 324 valid signatures to force a recall vote.
Last month, a jury acquitted Keyes on charges of attempting to influence a public servant and attempting to commit a hazardous waste violation.
Prosecutors alleged that Keyes spilled a 55-gallon barrel filled with hydraulic fluid during a raid of a methamphetamine lab, then lied about it to Otero County Health Department officials.
