Facebook said it has restored the “break up Facebook” ads it took down — but not before Sen. Elizabeth Warren claimed they proved her point about the social networking giant’s dominance.

The Massachusetts Democrat and presidential candidate called for a breakup of Facebook, Google and Amazon last week, outlining how her administration would lay out an antitrust case against the companies and pursue reversing their acquisitions of Instagram, Waze, Whole Foods and more. Starting Friday, her campaign paid for ads touting her plan on Facebook, and Politico reported Monday that the company took some of the ads down.
