The "passage" shows how it tries to ask Mr. Chairman to address an issue of injustice. This was actually a speech given by <em>Barbara Jordan,</em> an African American speaker. The speech she gave was meant to impeach President Richard Nixon for his association with the crimes that happened in the "Watergate scandal."
Remember that<u> the House of Judiciary Committee is responsible when it comes to impeachments.</u> So, this means that the audience most likely targeted in the speech are members of the House of Judiciary Committee, since they are the ones who takes over such event.
