Twitter to Ban Political Advertisements Associated Press SAN FRANCISCO - Twitter is banning all political advertising from its service, saying social media companies give advertisers an unfair advantage in proliferating highly targeted, misleading messages. Facebook has taken fire since it disclosed earlier in October that it would not fact-check ads by politicians or their campaigns, which could allow them to lie freely. CEO Mark Zuckerberg told Congress last week that politicians have the right to free speech on Facebook. The issue arose in September when Twitter, along with Facebook and Google, refused to remove a misleading video ad from President Donald Trump's campaign that targeted former Vice President Joe Biden, a leading Democratic presidential candidate. .
