A Parkland victim's parents were taken out of Congress last week, days before another mass shooting.
Manuel and Patricia Oliver interrupted a House gun regulations committee hearing last Thursday.
Now, just days later, another mass shooting has left three schoolchildren and three adults dead in Nashville, Tennessee.
Manuel and Patricia Oliver, parents of 17-year-old Parkland, Florida, shooting victim Joaquin Oliver, attended a House committee hearing on gun regulations last Thursday, NBC reported.
The mass shooting marks the 129th recorded this year, according to Brady, a non-profit working to prevent gun violence.
