A Fox Business Network executive on Sunday condemned the appearance of a guest on one of the network’s leading shows, “Lou Dobbs Tonight,” after the guest’s remarks were linked to anti-Semitism.
The guest, Chris Farrell of the conservative Washington group Judicial Watch, claimed the caravan of refugees now traveling in southern Mexico was funded by George Soros, a billionaire philanthropist and Democratic donor who has frequently figured in right-wing and anti-Semitic conspiracy theories.
Mr. Soros, who is Jewish, was also accused by Mr. Farrell of influencing the State Department. The episode was originally broadcast on Thursday but was shown again on Saturday night, after the shooting at a Pittsburgh synagogue that claimed 11 lives.
After the attack, Mr. Farrell’s comments created a firestorm on social media, with commenters on Twitter condemning Mr. Farrell and, in turn, Fox Business and “Lou Dobbs Tonight.”
In a statement on Sunday, Gary Schreier, senior vice president for programming at Fox Business, said, “We condemn the rhetoric by the guest on ‘Lou Dobbs Tonight.’” He added, “This episode was a repeat which has now been pulled from all future airings.”
According to Fox, Mr. Farrell will no longer be booked on either Fox Business Network or Fox News Channel.
The man accused in the Pittsburgh shooting, Robert Bowers, had a history of anti-Semitism, the authorities said. Cesar Sayoc Jr., who is accused of mailing pipe bombs to CNN and leading Democrats, also targeted Mr. Soros with a device sent to his home in Westchester County.
As the figurehead in a supposed global conspiracy that includes politicians and leaders of finance, Mr. Soros has been the focus of attacks, many of them anti-Semitic.
Earlier last week, Mr. Dobbs tweeted twice claiming that bomb threats aimed at the news media and prominent Democrats were false. He later deleted the tweets.
