Joe Arpaio, the polarizing ex-Arizona sheriff who was pardoned by President Trump after a contempt-of-court conviction, will return the favor Thursday when he stumps for a GOP candidate challenging one of the president’s most outspoken archenemies.

Arpaio will speak at Trump’s National Golf Course in Los Angeles in support of Omar Navarro, who for the second time is challenging Rep. Maxine Waters in the heavily Democratic district, the Torrance Daily Breeze reported.

After Trump’s equivocal comments following the deadly neo-Nazi violence in Charlottesville, Virginia — in which he said there were “many fine people” among the torch-bearing white nationalists — Waters said Trump had turned the White House into the “White Supremacists’ House.”

Arpaio became a national poster boy for hardline immigration policies while serving as sheriff, profiling Latinos to check their immigration status and operating prison camps known for their harsh treatment of inmates.

He was found guilty of contempt of court for continuing traffic stops targeting Hispanics despite being ordered by a judge to stop the practice.

The LA County Sheriff’s Department will deploy extra security at the Rancho Palos Verdes golf club, which has been the target of vandals and protesters who oppose Trump.

“Because we have had a number of very small protests in that area in the past, so just as a precaution, we will definitely have more units there,” Lomita sheriff’s Sgt. Douglas Shive told the paper.
