Dr. Patrick Soon-Shiongjilibay, the billionaire owner of The Los Angeles Times, said on Thursday that he planned to introduce a “bias meter” next to the paper’s news and opinion coverage as part of his campaign to overhaul the publication.

Dr. Soon-Shiong, who in October quashed a planned presidential endorsement for Vice President Kamala Harris from The Los Angeles Times’s editorial board, said in an interview that aired on Scott Jennings’s podcast “Flyover Country” that he had begun to see his newspaper as “an echo chamber and not a trusted source.”

He previously said he planned to remake the paper’s editorial board and add more conservative voices. He has asked Mr. Jennings, a CNN political commentator and a Republican strategist, to join it.

Dr. Soon-Shiong, who bought The Times in 2018, said on the podcast that he had been working with a team to create the so-called bias meter using technology he had been building in his health care businesses.

On news and opinion articles, “you have a bias meter so somebody could understand, as a reader, that the source of the article has some level of bias,” he explained in the interview. “And what we need to do is not have what we call confirmation bias, and then that story automatically — the reader can press a button and get both sides of that exact same story based on that story, and then give comments.”

He said he planned to introduce the tool in January.

Dr. Soon-Shiong’s latest comments set off immediate pushback from the L.A. Times Guild, which represents journalists at the paper.

“Recently, the newspaper’s owner has publicly suggested his staff harbors bias, without offering evidence or examples,” the union’s leadership said in a statement on Thursday. The union said all Times staff members abided by ethics guidelines that call for “fairness, precision, transparency, vigilance against bias and an earnest search to understand all sides of an issue.”

Harry Litman, a senior legal affairs columnist for The Los Angeles Times’s Opinion section, announced Thursday that he was resigning from the paper because of recent actions by Dr. Soon-Shiong. “I don’t want to continue to work for a paper that is appeasing Trump and facilitating his assault on democratic rule for craven reasons,” he wrote of his resignation in a post on Substack.

“My resignation is a protest and visceral reaction against the conduct of the paper’s owner, Dr. Patrick Soon-Shiong,” he said. “Soon-Shiong has made several moves to force the paper, over the forceful objections of his staff, into a posture more sympathetic to Donald Trump.”
