Reporting on Friday revealed that Facebook knowingly allowed a digital marketing firm tied to a pro-Trump group to release a series of ads purporting to be from a fake left-wing organization ahead of the 2018 midterm elections, while election officials failed to investigate the group at the time. As The Guardian reported, a right-wing marketing firm called Rally Forge ran a $5,000 ad campaign beginning just days before the 2018 election, showing ads promoting Green Party candidates in an effort to split the Democratic vote and help Republicans in several close races. The ads were purported to be placed by a group called America Progress Now and expressed support for democratic socialism.
