When the congress held hearings on climate change they did not ask outside experts to ask questions but tried on their own to understand the science and they looked inept. When they held hearings on social media they did not understand the intricacies of algorithms. But now when investigating the legal aspects of the attorney general report which they as lawyers are qualified to do they are asking for outside lawyers to help. If they ask questions they only get 5 minutes and it is difficult to properly cross examine in this short time. Outside lawyers can have more time.
