EVERYONE'S TALKING

ALSO IN THE HEADLINES

• Time to testify. A judge has ruled that Camille Cosby can be deposed in a lawsuit brought by seven women who allege that her husband, Bill Cosby, sexually assaulted them. People

• Rough road for GM. A different judge said that a lawsuit may proceed against General Motors, led by CEO Mary Barra, over the automaker's faulty ignition switches. This case—and five similar suits expected to go forward this year—opens GM up to possible punitive damages. WSJ

• Sheryl shares. In a New Year's Facebook post, Sheryl Sandberg wrote about a circle of female friends she has known since childhood. The Facebook COO credits these women for helping her "choose life and meaning" after the death of her husband, and hopes readers will "find the Circle that supports you—and cherish the moments of joy in each day."

• Cruise controller. Crystal Cruises CEO Edie Rodriguez talks to Fortune about being the only woman to head a luxury cruise line, traveling to more than 100 countries, and having a “triple A New York” personality. Fortune

• Score one for women. While FIFA, soccer's governing body, recently announced that it's accepting applications for a training program designed to put more women in leadership roles, current and former soccer stars—including Abby Wambach and Carli Lloyd—are pushing for the organization to take bigger, more concrete steps to advance women.
