The US president, Donald Trump, has tied the two shootings in Ohio and Texas to mental illness and video games.
Mr Trump, while speaking to press, said we must stop the glorification of violence in our society, this includes gruesome and grisly video games that are now commonplace.
Nikolas Cruz, who killed 17 at Marjory Stoneman Douglas High School in Florida in 2018, reportedly played violent video games up to 15 hours a day.
