Facebook CEO Mark Zuckerberg fired back at Tim Cook, arguing the Apple CEO's recent criticism about the social media company and its handling of the Cambridge Analytica scandal was "extremely glib."

Cook criticized Facebook last week during an interview with Recode's Kara Swisher and MSNBC's Chris Hayes, saying he "wouldn't be" in Zuckerberg's situation — hemorrhaging shareholder value and facing regulatory probes.
