Google didn't immediately respond to a request for comment. 

Facebook was represented by Neil Potts, the social network's public policy director, who also testified in the hearing on Tuesday. Twitter sent Carlos Monje, Jr., director of public policy and philanthropy for the US and Canada. Google had offered to send Max Pappas, the search giant's head of conservative outreach, but a source familiar with the situation said the committee rejected his appearance.
