Joe Arpaio, the former sheriff from Arizona who has become a national symbol of divisive immigration politics and hardline policing tactics, is scheduled to speak Thursday at Trump National Golf Club in support of a candidate for Congress.

The Los Angeles County Sheriff’s Department plans to deploy extra personnel around the Rancho Palos Verdes golf club, which itself has been the target of vandals and political activists who oppose President Donald Trump.

Arpaio, who was pardoned by the president in August following his contempt of court conviction a month earlier, is making an appearance on behalf of Omar Navarro, a South Bay Republican making a second long-shot bid to unseat South Bay Rep. Maxine Waters.

Navarro lost handily to Waters in the November 2016 election in the heavily Democratic 43rd Congressional District, which stretches from Westchester to Torrance and inland to South Los Angeles. Since last year’s election, Waters has become a national figure in the resist-Trump movement and regularly calls for his impeachment.

Arpaio, the six-term sheriff of Maricopa County, Arizona, until he was ousted by voters in 2016, was convicted in a case that grew out of his department’s detention of people based solely on suspicion about their immigration status and without evidence that a law had been broken.

A federal judge in 2011 ordered Arpaio to stop the practice, which the former sheriff ignored, a move that ultimately led to his conviction.

Trump has said he considers Arpaio a friend, and he supported the sheriff even before he pardoned him despite his history of harsh police tactics.

The Lomita sheriff’s station, which provides law enforcement on the Palos Verdes Peninsula, said it hasn’t received any indication that a large-scale protest is planned for the event, but extra staff will be provided as a precaution due to Arpaio’s notoriety.

“In anticipation of any issues, 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,” said Lomita sheriff’s Sgt. Douglas Shive.

Trump National, which is a public course, has occasionally been the target of activists since Trump’s election. In May, about 200 people lay on the course to spell out the word “RESIST!” Earlier this year, another group used gardening tools to carve the words “NO MORE TIGERS NO MORE WOODS” into one of the greens.

Shive said there likely will be a mix of about six uniformed deputies and reserves at the Thursday night event, which will be from 6-10 p.m., with Arpaio scheduled to speak about 8.

The city of Rancho Palos Verdes will foot the bill for the extra sheriff’s patrols, but it’s not clear yet what the total cost will be, City Manager Doug Willmore said in an email.

Lili Amini, general manager for Trump National Golf Club, did not return a call requesting comment.
