Megyn Kelly, the Fox News star who’s had a contentious relationship with President-elect Donald Trump, said Tuesday that she’s leaving the network to work for NBC News, where she will host a daytime talk show and a weekend newsmagazine, as well as contribute to breaking news coverage. NBC News made the announcement Tuesday, ending months of speculation over whether she would re-up with Fox, where she has flourished while suffering bruised feelings in recent months, or start a new chapter in her career.
