The ongoing feud between President Donald Trump and California Gov. Gavin Newsom flared up once again Sunday — sparked by a fresh round of social media barbs — including an image of a zombie Gov.

Trump grabbed attention by sharing an image of a mock California license plate reading “NEW-SCM,” featuring Newsom in the middle depicted in a zombie-like state.

The post racked up more than 135,000 views after Newsom’s press office reposted the dig and wrote, “Even a Zombie Newscum still looks healthier than our current President. #PrayersforGrandpa.”

Trump’s jab came in response to Newsom’s own social media swipe earlier that day, when the governor’s press office posted an image of Trump flanked by security alongside what appeared to be an alien figure in chains.

“The President of the United States just posted this. Do you think he’s lost it?” the caption read.

The escalating online spat is just the latest in a long-running war of words between the two political heavyweights.

Back in January, Trump blasted Newsom as a “Lame Duck” making a “mockery of himself” on the world stage during the World Economic Forum in Davos, Switzerland.

Trump accused Newsom of prioritizing international attention while California continued to battle crime, drought, and wildfire devastation.

“He should finish his monstrously ‘over budget and behind schedule’ Railroad, from San Francisco to L.A., one of the Greatest Public Disasters in History, and focus on stopping Crime in the streets of California Cities — Then finish out his term, and GO HOME!” Trump wrote at the time.

The White House also previously told The California Post that Newsom should “stop undermining the United States on the world stage” and focus on fixing his “broken” home state.

Newsom, meanwhile, has continued firing back, with his press office calling Trump a “deranged, habitual liar” and mocking his “little fingers” after the president launched a fraud investigation into California.

As both men continue trading increasingly personal attacks, their bitter political rivalry shows no signs of cooling down — especially with Newsom’s eyes on a run at The White House.
