This April 26, 2017, photo shows the Twitter app icon on a mobile phone in Philadelphia. Twitter is enlisting its users to help combat misinformation on its service by flagging and notating misleading and false tweets. The pilot program unveiled Monday, Jan. 25, 2021 called Birdwatch, allows a preselected group of users for now, only in the U.S. who sign up through Twitter. Those who want to sign up must have a U.S.-based phone carrier, verified email and phone number, and no recent Twitter rule violations. (AP Photo/Matt Rourke) **FILE**
