The man accused of sparking the deadly Palisades Fire on New Year's Day in Southern California frequently made anti-Trump social media posts and shared how global warming was causing climate change.

One story Jonathan Rinderknecht, 29, shared was from ProPublica, titled "Climate Change Will Force a New American Migration," which pictured a hillside on fire in California.

He also shared another article titled "Senator Kamala Harris Says Meat Is Destroying the Planet," and also posted a link to contribute to former President Joe Biden's election campaign in 2020.

Rinderknecht's other posts include pictures of Trump supporters crying after losing the 2020 election, as well as sharing a post that claimed President Donald Trump inherited a great economy from former President Barack Obama, but he "destroyed it" during COVID-19.

WHO IS JONATHAN RINDERKNECHT, PALISADES FIRE SUSPECT ACCUSED OF SPARKING DEADLY BLAZE?

Rinderknecht frequently posted about climate change and shared another story in 2020 titled "The Great Climate Migration has begun." In another, he shared a story titled "Summers could become ‘too hot for humans.'"

While Rinderknecht didn't post many pictures, one picture from 2014 shows him wearing face paint depicting a skull with his mouth open, as well as fake blood dripping down his neck.

Rinderknecht was arrested on Tuesday in Florida and charged with destruction of property by means of fire, acting United States Attorney Bill Essayli said. A federal judge ordered that he remain behind bars on Thursday after prosecutors said Rinderknecht has traits of an arsonist.

"The complaint alleges that a single person’s recklessness caused one of the worst fires Los Angeles has ever seen, resulting in death and widespread destruction in Pacific Palisades," Essayli said. "While we cannot bring back what victims lost, we hope this criminal case brings some measure of justice to those affected by this horrific tragedy."

Federal authorities said Rinderknecht worked as an Uber driver in Los Angeles from New Year's Eve 2024 to New Year's Day 2025, adding that two of his passengers expressed that "he appeared agitated and angry that night after dropping off a passenger in Pacific Palisades."

After allegedly sparking the fire after parking at the Skull Rock Trailhead, Rinderknecht called 911, then asked ChatGPT: "Are you at fault if a fire is lift [sic] because of your cigarettes?"

ChatGPT, according to the complaint, responded with "Yes," and explained.

While prosecutors allege that Rinderknecht sparked the Lachman Fire, which was put out on Jan. 2, heavy winds reignited underground embers, which sparked the Palisades Fire. In total, the Palisades Fire claimed the lives of 12 people and left many displaced.

FIRST ON FOX: U.S. Citizenship and Immigration Services (USCIS) saw more than 20,000 applicants in less than two weeks for "Homeland Defender" roles as the Department of Homeland Security ramps up their hiring campaign.

The recruitment campaign at USCIS began Sept. 30, and sources at the agency say a hiring campaign of this scale has never been done before.

"I am thrilled with the tremendous response we have received from fiercely dedicated, America-first patriots who want to serve as Homeland Defenders," USCIS Director Joseph Edlow told Fox News Digital.

"In mere days, more than 20,000 Americans have stepped forward, ready to serve on the frontlines to protect our nation’s sovereignty and restore integrity to our immigration system after four disastrous years of failed Biden administration immigration policies," Edlow explained to Fox. "These applicants are not just candidates—they are guardians of our values, prepared to defend our homeland. We look forward to bringing on this group soon."

The role of a Homeland Defender is to determine whether legal migrants are eligible for green cards, extended visas, or citizenship. Homeland Defenders were previously titled "Immigration Services Officer," though the position was rebranded under the Trump administration. 

14,021 applications were submitted to the USCIS Service Center Operations Directorate and 8,627 applications were submitted to the USCIS Field Operations Directorate. 

The USCIS website touts a potential $50,000 signing bonus, remote work, and no college degree required. 

Fox News Digital exclusively reported that Immigration and Customs Enforcement (ICE) recruiting also saw a massive uptick in applications, hitting 141,000 in early Sept.

BLUE STATE IN THE HOT SEAT AFTER ICE BUSTS ILLEGAL IMMIGRANT WITH 'NO NAME GIVEN' ON LICENSE

Immigration officers across various agencies under DHS have faced scrutiny and security threats by protestors and Democrats alike. 

Secretary Kristi Noem said that ICE agents "are now facing a 1000% increase in assaults against them as they risk their lives to arrest the worst of the worst criminal illegal aliens" in August.

The Trump Administration’s recent deployment of agents to Chicago has been widely criticized by Illinois governor J.B. Pritzker, and has faced some legal challenges as ICE officers make arrests.

NOEM: TRUMP ADMINISTRATION DOUBLING DOWN WITH NEW FEDERAL FACILITIES IN CHICAGO, PORTLAND

U.S. District Judge Jeffrey Cummings, a Biden-appointed judge, tightened ICE’s ability to make warrantless arrests in a Chicago federal court on Tuesday. President Donald Trump has repeatedly threatened to send National Guardsmen to rein in the city’s violent crime amid ICE agent deployment, a move which could also face legal hurdles.

As of late Sept., DHS said that 1.6 million illegal immigrants have been voluntarily self-deported, while 400,000 were removed by federal law enforcement.

"The Trump administration is on pace to shatter historic records and deport nearly 600,000 illegal aliens by the end of President Donald Trump’s first year since returning to office," the agency said in a statement.
