Donald Trump calls for crackdown on video games, immigration reform in the wake of two mass shootings

US President Donald Trump has condemned racism and white supremacy while also calling for a crackdown on violent video games in the wake of two mass shootings in Texas and Ohio.

In a speech from the White House on Tuesday, Trump said it is "too easy" to become surrounded by a culture of violence.

"We must stop the glorification of violence in our society. This includes the gruesome and grisly video games that are now commonplace," he said.

"It is too easy for troubled youth to surround themselves with a culture that celebrates violence. We must stop or substantially reduce this and it has to begin immediately."

The shootings in El Paso, Texas and Dayton, Ohio over the weekend left a total of 39 dead in less than 14 hours.

The El Paso shooter posted a manifesto online before the rampage, which according to authorities, was filled with anti-immigrant rhetoric. 

"In one voice, our nation must condemn racism, bigotry and white supremacy. These sinister ideologies must be defeated," said Trump on Tuesday.

"Hate has no place in America. Hatred warps the mind, ravages the heart and devours the soul."

On Twitter, Trump suggested stronger background checks paired with "desperately needed immigration reform," to stop gun crime. 

Trump also urged the Justice Department propose legislation to ensure the shooters face the death penalty.

"This capital punishment [should] be delivered quickly, decisively and without years of needless delay."

There have been 255 mass shootings in America this year.
