The battle for Los Angeles City Hall is getting uglier—and far more personal—as mayoral challenger Spencer Pratt takes direct aim at incumbent Mayor Karen Bass over her past ties to communist Cuba.

In a blistering post on X that quickly caught fire online, Pratt revived long-running questions about Bass’s political past, highlighting reports that she traveled to Fidel Castro’s Cuba as a young activist and allegedly participated in programs tied to radical left-wing organizing.

For conservatives frustrated by years of failed leadership in Los Angeles, rising homelessness, crime concerns, and progressive governance, Pratt’s latest attack landed like gasoline on an already raging fire.

And he didn’t hold back.

“When I was in my 20s, I was on a TV show,” Pratt wrote. “When Karen Bass was in her 20s, she was training in terrorist tactics and guerrilla warfare with communists in Cuba.”

The remark referenced historical reporting about Bass’s involvement with the Venceremos Brigade, a controversial activist organization that organized trips for young Americans to Cuba during the Cold War.

As Pratt surges in polling and fundraising, what once looked like a symbolic candidacy is increasingly beginning to resemble a real threat to Bass’s hold on City Hall. That reality has transformed the mayoral contest into one of the most heated political battles Los Angeles has seen in years.

At the center of Pratt’s criticism was an older report from the *Los Angeles Times*, which discussed intelligence documents related to Bass’s activism in the 1970s.

According to excerpts Pratt highlighted, one intelligence document claimed Bass traveled to Cuba with the Venceremos Brigade, an organization critics long accused of promoting pro-Castro ideology while exposing young American activists to revolutionary politics.

The report alleged the group trained “revolutionary-prone Americans” and exposed participants to guerrilla-style political organizing while officially framing the trips as agricultural labor and cultural exchanges.

Another portion of the reporting claimed Bass returned to the United States carrying communist propaganda materials, though the allegations themselves have remained politically contentious for years.

Still, for Pratt and many conservatives, the larger point is impossible to ignore.

How, they ask, does someone with deep ties to radical left-wing activism end up governing one of America’s largest cities?

Critics argue Los Angeles itself may already provide the answer.

Years of progressive policymaking have left residents grappling with homelessness crises, rising affordability concerns, public safety frustrations, and infrastructure problems that many blame squarely on Democrat leadership.

To Pratt supporters, Bass’s political history helps explain the ideological roots of policies they believe have pushed Los Angeles into decline.

Online reactions to Pratt’s post were swift and fierce.

Many commenters expressed disbelief over Bass’s past involvement with Cuba, with some pointing to additional reporting from national outlets that examined her controversial activism during previous political campaigns.

Others argued that Los Angeles voters deserve a fuller accounting of Bass’s political background as they head toward a high-stakes election.

Meanwhile, Bass allies accuse Pratt of engaging in political theater and dredging up decades-old controversies to distract from policy discussions.

But Pratt appears more than willing to lean into the fight.

As frustration grows over the direction of Los Angeles, the race is increasingly becoming a referendum not only on crime, homelessness, and city management—but also on competing visions for the city’s future.

For Pratt, the message is clear: if Los Angeles wants change, voters should take a hard look at the ideology that helped shape the leadership already in power.

And in a city long dominated by Democrats, that argument may be finding more traction than many expected.
