Fox News, Gretchen Carlson settle lawsuit

Gretchen Carlson is the woman who brought down Roger Ailes, and now, she has an apology from Fox, and is settling with the network for a reported $20 million. Carlson sued Roger Ailes alleging harassment and retaliation in July, an action that led to his resignation, and prompted others to come forward about a pattern of harassment.
