Vice President Kamala Harris is visiting Tennessee on Friday to show her support for the "Tennessee Three" - Reps. Justin Jones and London Lamar, both African American, and Rep. Gloria Johnson, who is white - who were expelled from the state House in retaliation for their role in a protest calling for more gun control. Harris will meet with the expelled lawmakers and young people advocating for tougher gun control laws. The expulsion has been widely condemned by gun control advocates, raising questions about the state's commitment to protecting the rights of its citizens.
