(CNN) After two shootings in less than 24 hours killed 30 people and injured dozens more over the weekend, President Donald Trump addressed the nation Monday morning, condemning "racism, bigotry and white supremacy" but failing to directly address his own rhetoric when doing so.

Among the potential causes for both shooters' actions in El Paso, Texas, and Dayton, Ohio, Trump targeted video games. "We must stop the glorification of violence in our society. This includes the gruesome and grisly video games that are now commonplace. It is too easy today for troubled youth to surround themselves with a culture that celebrates violence," he said.

Trump's comments echoed those from House Minority Leader Kevin McCarthy, a California Republican who told Fox News on Sunday that "the idea of these video games that dehumanize individuals to have a game of shooting individuals and others -- I've always felt that is a problem for future generations and others."

Facts First: While some leading psychological organizations in the US say that children should not play violent video games because it may lead to aggressive behavior, there are no findings from research that demonstrate a direct connection between people playing violent video games and mass shootings.

This is not the first time that Trump, or other politicians both Democratic and Republican, have cited video games as one of the potential causes for an American mass shooter's actions.
