@pbsnews: Republican lawmakers filed a resolution to expel three Democratic representatives who participated in a protest at the state capitol calling for stricter gun laws. Representatives Justin Jones, Gloria Johnson and Justin Pearson have already been stripped of their committee assignments. Only two other Tennessee House members have been expelled since the 1860s. Meanwhile, students and advocates continue to protest for gun reform at the state capitol after three 9-year-olds and three adults were killed in the Covenant mass shooting last month. #covenantschool #covenant #guncontrol #gunlaws #gunlegislatin #tennessee #tennesseelawmakers #justinjones #justinpearson #gloriajohnson #tennesseestatecapitol #walkout #gunreform #housemembers #pbs #news #pbsnewshour #newshour #tennesseeprotest
