United States President Donald Trump has condemned “racism, hatred and white supremacy” in an address following mass shootings that left 29 dead in Texas and Ohio.

Trump said a “wicked man” went to a Walmart store in El Paso, Texas, in that mass shooting and said a “twisted monster” carried out the shooting in Dayton, Ohio, just hours later.

“These barbaric slaughters are an assault upon our communities, an attack upon our nation and a crime against all of humanity,” Trump said.

“In one voice, our nation must condemn racism, bigotry and white supremacy,” Trump said.

While not proposing any major gun control legislation, he said the nation needs to strengthen mental health laws.

“Mental illness and hatred pull the trigger, not the gun,” he said.

“Today I am also directing the Department of Justice to propose legislation ensuring that those who commit hate crimes and mass murders face the death penalty and that this capital punishment be delivered quickly, decisively…” the president added.

Trump said the country needs to put partisanship aside, saying it is “not up to mentally ill monsters, it is up to us.”

“The perils of the internet and social media cannot be ignored and will not be ignored,” the president said, blaming “gruesome and grizzly video games” for the “glorification of violence in our society.”
