Why do social media CEOs have to go through the U.S. Senate hearing?

Question

European here, I was always confused watching U.S. Senate hearings with social media CEOs having to explain and be almost interrogated and accused of someone’s suicide from supposedly “watching content on the platform”. Why do they need to do that and is it only U.S. thing or does it happen somewhere else?

Answer 1

They are not compelled to unless they have been formally subpoenaed. Sometimes not even then.
