MediaPost, the group will also warn lawmakers that tightening those rules won't necessarily affect the spread of "fake news" online.
"Enhancing the existing framework by clarifying the responsibility of publishers, platforms, and advertisers in making available these disclosures to the public would create greater legal certainty across the industry and provide valuable information," IAB CEO and President Randall Rothenberg plans to tell Congress in a prepared statement.
Rothenberg will testify Tuesday before the House Oversight subcommittee on information technology, which is slated to hold a hearing about online political ads. David Chavern, CEO of News Media Alliance, will also testify Tuesday, as well as representatives from the Center for Competitive Politics, and the Brennan Center for Justice, among others.
The hearing was announced late last week, shortly after Senators Amy Klobuchar (D-Minnesota), Mark Warner (D-Virginia) and John McCain (R-Arizona) introduced The Honest Ads Act, which aims to subject large web companies to the same disclosure rules as broadcasters. Earlier this month, the Federal Election Commission invited public comments about whether online ads should be required to include the same disclaimers as TV and newspaper ads.
Much of the activity on Capitol Hill stems from revelations about the Kremlin's involvement in the 2016 presidential election. Facebook said last month that accounts connected to Russia purchased around 3,000 political ads for $100,000 between June of 2015 and May of 2017. Twitter found 200 accounts connected to the ones identified by Facebook, while Google reportedly may have run at least $50,000 worth of ads connected to Russia.
