Facebook chief operating officer Sheryl Sandberg criticized Twitter on Thursday over the company's decision to block Rep. Marsha Blackburn (R-Tenn.) from promoting an advertisement on the social media site that Twitter had deemed “inflammatory.”

“Marsha Blackburn ran an ad, which is launching her campaign for Senate. And in that ad there’s a lot of positions that people don’t like — that I don’t like,” Sandberg said in an interview with Axios that was broadcast on Facebook Live. “But the question is: should divisive political or issue ads run? Our answer is yes.”
