Mika Brzezinski, co-host of MSNBC's "Morning Joe," said Saturday that she would pull book deals from a company associated with Harvey Weinstein if he does not resign following accusations from multiple women about sexual harassment.

"I have a three-book deal with Weinstein Books, through Hachette," she tweeted Saturday. "I can't go forward with those books unless Harvey resigns."

Brzezinski is the author of several books which have explored themes about women's roles in the workplace and about body image, including Knowing Your Value and Obsessed.

The New York Times this week released an in-depth investigation with interviews from women who allege that Weinstein, co-founder of the Weinstein Company, sexually harassed them and made unwanted advances, and paid some of them off to keep quiet. Weinstein has taken a leave of absence from the company and has framed his behavior as stemming from his "coming of age" during the 1960s and 1970s, when he said workplace behavior was different.

Another woman, TV anchor Lauren Sivan, came forward Friday to say that Weinstein masturbated in front of her without her consent.

Much of Hollywood has been silent since the allegations surfaced.
