It used to be unusual for a top tech executive to face tough questions in front of the legislature on Capitol Hill. That has changed in the last few years. Now the executives of Facebook, Google and Twitter are old hands at hearings in Congress.
Wednesday's hearing marks the fifth time Facebook's Mark Zuckerberg testifies before lawmakers. the third time for Sundar Pichai by Google; and the third for Twitter's Jack Dorsey. All appearances have taken place in the past three years.
The hearings have been a boon to Washington law firms preparing the executives. WilmerHale, for example, has been on Facebook for years and has prepared Mr. Zuckerberg for all hearings since his first hearing in March 2018.
