Facebook’s Mark Zuckerberg is testifying before congress next week, but before he goes, he has a message for lawmakers: He supports political advertising regulation. 

“Election interference is a problem that’s bigger than any one platform, and that’s why we support the Honest Ads Act,” Zuckerberg said in a Facebook post. “This will help raise the bar for all political advertising online.”

The Honest Ads act is a senate bill that would require tech companies to disclose how political ads were targeted and how much they cost. It’s sponsored by Senator Amy Klobuchar, a Democrat from Minnesota, and and Mark Warner, a Democrat from Virginia. The act was drafted in response to Russian trolls abusing Facebook and other online platforms during the 2016 US presidential election to sow discord among Americans. 

In a statement, Warner praised Facebook for supporting more transparency around ads. He said that most of the Kremlin-backed ads on Facebook during the election season didn’t specifically mention then-candidates Hillary Clinton or Donald Trump. Instead, they tried to drive divisions by mentioning hot-button issues like guns, LGBT rights and immigration.

“That’s why today’s announcement by Facebook is so important,” he wrote. “I would encourage all of the platform companies to follow suit as we work toward making the Honest Ads Act the law of the land, ensuring that political ads sold online abide by the same disclosure rules as TV and radio ads.” 

Klobuchar’s office didn’t immediately return a request for comment.
