Sheryl Sandberg on alleged Facebook cover-up
Facebook's top executives are fighting back against a bombshell New York Times report that questions how they handled security issues surrounding the site. Wednesday's report says CEO Mark Zuckerberg and COO Sheryl Sandberg helped hide problems within Facebook, and used a lobbying firm to attack critics. In an interview with "CBS This Morning" co-host Norah O'Donnell, Sandberg strongly denied the article's claims, saying "the allegations in this piece are very serious and absolutely false."
