Warren, who is running for president in 2020, announced a proposal last week to break up Silicon Valley's largest companies, saying that they have too much power.

On Monday, Politico reported that some of the Massachusetts lawmaker's ads had been removed from Facebook.

“We removed the ads because they violated our policies against use of our corporate logo. In the interest of allowing robust debate, we are restoring the ads," the company said in a statement to The Hill after restoring the ads on Monday.

Andy Stone, a spokesman for Facebook, noted that several other ads related to her plan to break up Facebook, Instagram and WhatsApp, among other tech conglomerates, were unaffected.

Stone told The Hill Tuesday that their previous statement on Warren's ads remains the same.

Warren is the first major 2020 candidate to call for breaking up large tech companies such as Facebook, Google and Amazon, though the idea has spread among progressives recently, driven by concerns about data privacy and the potential use of social media as a tool to spread disinformation.
