Los Angeles Mayor Karen Bass accidentally blurted out the word 'firef*ck' while defending her handling of the California wildfires during a heated debate with political rivals.

The incumbent mayor faced off Wednesday night against mayoral hopeful Spencer Pratt and challenger Nithya Raman, with 79 percent of viewers declaring Pratt the winner thanks to his brash debate style, as reported by NBC News.

She was grilled by the moderator over accusations she prioritized a firefighters union pay increase over rebuilding funds, and was pressed to clarify claims that fire engines had been described as 'inoperable.'

Bass immediately shifted blame to the fire chief at the time, Kristin M Crowly, who the mayor said ordered more than 1,000 firefighters home, leaving enough trucks but not enough responders to man them.

It was when she grew increasingly defensive over her handling of the 2025 fires that the F-bomb slipped out mid-sentence. 

'So yes, there were firetrucks that were broken, but there were also firef*cks - trucks - that were out of use because she had sent the firefighters home,' Bass said, quickly correcting her mispronunciation.

'You are correct, there was supposed to have been deployment and pre-deployment in the area - that did not happen,' she added. 'But the same way LA was not prepared, neither was the county.'

Pratt, her Republican rival, blamed Bass for the fallout from the deadly Palisades Fire, which destroyed his $3.8 million home and more than 11,000 properties across Southern California last January.

'I blame this person for burning my house down,' the 42-year-old reality TV star declared during the debate.

Pratt has been a vocal critic of Bass's wildfire response, grounding his campaign in allegations of mismanagement after the fires burned down his home he shared with wife Heidi Montag.

He posted a campaign video just last month comparing the neighborhoods of Bass and Raman before cutting to an Airstream trailer next to his destroyed property. 

'They let my home burn down. I know what the consequences of failed leadership are,' the Republican said in the footage.

'That's why I am running for mayor, for my sons and the rest of these Angelenos that want to stop these corrupt politicians from destroying our city,' he added. 'We are going to get the golden age of Los Angeles back.'

His comments were in regards to Bass's absence during the unfolding crisis, including travel to Ghana amid a powerful windstorm and questions over whether sufficient pre-fire resources were deployed. 

The mayor also approved roughly $17.6 million in cuts to the city’s fire department shortly before the tragedy. 

On Tuesday, in response to Pratt’s comments over the alleged bungling of the city’s response, Bass accused him of 'exploiting' the tragedy to score political points, according to Fox News.

'Honestly, before this, I had never heard of Spencer Pratt,' Bass told MeidasTouch during an interview.

'The thing I am concerned and feel about him is that I feel like he's exploiting the grief of people in the Palisades and I just think that's just reprehensible,' she added.

'That's the main thing and I think he is about his own celebrity - he's famous now again.'

It was revealed Tuesday that the LAFD union president filed a lawsuit against Bass, alleging she conducted a 'smear campaign' in response to his criticism of the city’s fire response resources, according to The New York Post.

Freddy Escobar, a 36-year veteran of the LAFD and head of the United Firefighters of Los Angeles Local 112 (UFLAC), launched a federal legal action against Bass and the City of Los Angeles.

In his complaint, Escobar claims that Bass and senior aides instructed fire officials to suggest to the media that he was being investigated for overtime issues, as part of an alleged effort to suppress his criticism of the fire budget.

Bass has maintained her argument that her experience in Congress and leading the wildfire response makes her better qualified than Pratt, whom she accused of not understanding 'how government works.'

She also pointed to climate change, saying 'hurricane-strength winds and no rain' are unusual conditions for LA and beyond. 

Her comments drew swift backlash. Roxanne Hoge called Bass’s response 'tone-deaf,' while attorney and strategist Elizabeth Barcohana accused the mayor of attacking a fire survivor who is 'living in a trailer on his burned-out lot.'

Former Trump campaign adviser Janiyah Thomas also criticized Bass, arguing Pratt’s personal losses give him legitimacy and accusing the mayor of being absent during the crisis. 

'I'm not sure if Karen Bass forgot she let my house burn down and my parents house burn down and I had actual neighbors burn alive across the street from my childhood home,' the reality star said.

'The only grief is my grief, my community's grief that I initially started this fight on behalf of,' he added.

'It's the most insane, psycho, diabolical thing I've heard in a minute - but it's not shocking.'
