Warren Buys Ad with Deliberate Lies to Test Facebook's Response

Elizabeth Warren bought a political ad on Facebook that purposefully includes false claims about Facebook’s chief executive, Mark Zuckerberg, and President Trump to goad the social network to remove misinformation in political ads ahead of the 2020 presidential election. In a series of tweets, the Democratic presidential candidate said she had deliberately made an ad with lies because Facebook had previously allowed politicians to place ads with false claims.
