Sean Hannity says a media watchdog is guilty of “liberal fascism” for targeting advertisers on his Fox News Channel show, as one company announced Wednesday that it would no longer hawk its wares there.

The Chicago-based Cars.com said that it had been “watching closely” and recently decided to suspend its backing of Hannity.

Hannity, the sole survivor from Fox’s once stable and powerful prime-time lineup, has been a strong backer of President Donald Trump and believes the president is under attack from media and opponents who want to destroy him. On Wednesday, Hannity said he would no longer talk about a discredited story involving a murdered Democratic National Committee chairman after speaking to the man’s family, and after Fox had earlier retracted an online story it had written about the case.

Uncertainty over whether Hannity would defy his network’s bosses over the story led to big ratings on Wednesday. The show reached 2.5 million viewers, or 50 percent more than it had for the same night a year earlier, the Nielsen company said.

On Wednesday, Hannity sent a steady stream of tweets that targeted Media Matters for America, the liberal lobbyists who a day earlier had posted a list of his show’s advertisers on its web site. Targeting a show’s advertisers is a potent line of attack in television; the swift abandonment of Bill O’Reilly’s advertisers last month after the revelation of settlements paid to women to quiet harassment charges was widely considered a factor in his firing by Fox.

Media Matters is “targeting my advertisers to silence my voice,” Hannity tweeted. “They hope to get me fired. Rush (Limbaugh), O’Reilly, (Glenn) Beck, (Don) Imus and now me.” He posted a series of links to articles about Media Matters’ funding, and ties to figures reviled by many conservatives, like George Soros and Bill Clinton.

Media Matters denied that it was mounting a pressure campaign focusing on Hannity’s advertisers. The organization’s president Angelo Carusone said he hadn’t spoken to any sponsors. He said he wanted advertisers to be aware of Hannity’s “volatility” as part of a general Media Matters campaign to get them to think about advertising on Fox; Media Matters hasn’t posted a list of sponsors for any other specific show.

Saying there’s no boycott campaign may be a distinction without a difference, however. Media Matters listed on its website more than 150 companies that had run commercials on “Hannity” in May, ranging from Lexus to Reddi-wip to Comedy Central. Hannity tweeted Wednesday that he’d spoken to several of his advertisers and they said they’d been “inundated” with emails urging them to stop running commercials on his show.

Cars.com said in a statement that its decision to advertise on a show doesn’t mean it agrees or disagrees with its content.

“We don’t have the ability to influence content at the time we make our advertising purchase,” the company said. “In this case, we’ve been watching closely and have recently made the decision to pull our advertising from Hannity.”

The company did not make clear when it made that decision or what about Hannity’s content influenced its executives. A company representative did not immediately return a call seeking comment.

By alerting his supporters about the list of advertisers, Hannity has played into his critics’ hands, Carusone said.

“He has demonstrated that he’s totally volatile and out of control,” he said. “Hannity has done more to create pressure for his advertisers than I have.”

Carusone suggested that Hannity is “acting out of fear and anxiety over the future of Fox News by preying on the fears and anxieties of his audience.”

“We’re not running a campaign to get him fired right now,” he said.

Hannity was active on Twitter before his show Tuesday, saying that he would discuss the case of murdered DNC staffer Seth Rich and his own future on Fox. It clearly paid off by drawing interest; his viewership was just under the 2.6 million reached by the current queen of prime-time cable television, Rachel Maddow, on MSNBC.

Hannity declined comment through a spokesperson Wednesday night. His show has an average viewership this year of 2.67 million.
