Getty Images/Business Insider Tucker Carlson has covered sexual-harassment allegations about Democratic-leaning figures while remaining quiet about accusations against his former Fox News colleagues. Many television personalities have recently found themselves forced to answer for former colleagues accused of sexual harassment or report on the allegations. The Fox News host Tucker Carlson says he has largely avoided covering sexual-harassment allegations against his former colleagues — such as those against the longtime CEO Roger Ailes, host Eric Bolling, and anchor Bill O'Reilly — because he did not have anything to add. "It's been thoroughly covered — those aren't secret stories," Carlson said in an interview after his appearance at Business Insider's IGNITION conference last week.

"I've never sexually harassed anybody, obviously, but self-righteousness is a really unattractive quality in people, and it tends to flower on television," Carlson said." And sometimes I do it, and I always regret it. So I really try to remember these are people, and all people with power tend to abuse their power — sexually, financially, in any context." He added: "But you ought to be able to tell the truth without being punished ... People who haven't done anything wrong are still worried and nervous, and if we can't say what we think, we've lost something."
