(CNN) What do United Airlines, White House Press Secretary Sean Spicer and Fox News host Bill O'Reilly have in common? They all bungled responses to public relations crises this week, says Lanny Davis, a lawyer and crisis management specialist. Speaking with CNN's Michael Smerconish on Saturday, Davis said United Airlines' response to a viral video of a passenger being dragged off a flight was a "textbook case of how to do everything wrong." Davis, whose past clients include Martha Stewart and the NFL's Washington Redskins, was particularly critical of United CEO Oscar Munoz. In his initial statement about the incident on Monday, Munoz only apologized for "having to re-accommodate ... customers." An email he later sent to United employees described the removed passenger as "disruptive and belligerent."PR expert says United bungled apology for forcibly removing passengerSays Sean Spicer broke "cardinal rule" of PR by comparing Syria's Assad to HitlerAdvises Bill O'Reilly to own up to mistakes and apologize
