Sen. Josh Hawley, R-Mo., sent a letter to Google CEO Sundar Pichai on Wednesday demanding answers in response to a recent study that found the tech giant’s email spam filtering algorithms exhibited political bias in 2020.

“New research reveals that your company makes it much harder for Republicans to reach their supporters even while your company makes it very easy for Democrats to reach theirs,” Hawley said, adding that the internet plays a crucial role for political campaigns to reach their voters.

Hawley went on to reference a study published last week by North Carolina State University’s Department of Computer Science titled, “A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020.”

For the extensive study, which took place from July 1, 2020 to Nov. 30, 2020, researchers created 102 email accounts on Gmail, Outlook, and Yahoo, and subscribed to two presidential candidates, 78 Senate candidates, and 156 House candidates.
