A data analytics company that threw Facebook policies into international scrutiny touted the success of digital advertising for an Iowa Congresswoman’s campaign.

In a post-2014 election report, Cambridge Analytica promoted successful digital advertising the firm created for U.S. Sen. Joni Ernst, a Republican who successfully ran against Iowa Democrat and incumbent Bruce Braley.

The ads were paid for by a political action committee run by U.S. Sen. Ted Cruz, which paid Cambridge Analytica $133,333 to create the ads, the Cedar Rapids Gazette reports.

Cambridge Analytica threw Facebook under fire after the company used information from 87 million Facebook users to create voter profiles, allegedly using the data improperly for President Donald Trump’s 2016 campaign.
