Trump Echoes ‘Fox & Friends’ on Shootings. The New York Post Dissents.

“These people are twisted,” he told the CNN anchor Jim Sciutto. “They’ll find ways around that.”

After noting that high-powered weapons “have been available” for decades, Mr. Urban added, “What has changed in American culture that makes people do what they’re doing today?”

The first law enforcement officer arrived at the scene of the El Paso massacre six minutes after the shooting started. In Dayton, where nine people were killed and more than two dozen were injured, the police shot and killed the assailant within one minute of the first gunshots.

Some conservative commentators focused on legislation pertaining to high-powered weaponry, but George P. Bush, a Republican who serves as the Texas land commissioner, highlighted the role played by white nationalists in mass shootings in his public statements on Sunday and in an article published on The Atlantic’s website on Monday.

In the article, headlined “White-Nationalist Terrorism Must Be Stopped,” Mr. Bush, the son of former Gov. Jeb Bush of Florida, referred to recent testimony by the F.B.I. director, Christopher Wray, to argue that “most of the terrorist attacks in the U.S. are a consequence of white-nationalist terrorism.”

David French, a prominent “Never Trump” conservative who flirted with a presidential run in 2016, went further in an article on the website of the right-wing magazine National Review, blaming Mr. Trump and certain quarters of Fox News for giving comfort to white nationalists.

“Think of the thrills, energy and inspiration they’ve experienced from the highest office in the land — and from parts of the most popular cable network in the land — since Trump came down the escalator in 2015,” Mr. French wrote.

Outside the United States, many global news organizations focused on American racism and Mr. Trump.

In Australia, a headline for an opinion article in The Sydney Morning Herald on Sunday declared, “US in the midst of a white nationalist terrorism crisis.” A column in the German publication Frankfurter Allgemeine Zeitung argued that Mr. Trump “has not withdrawn the poison from the political climate of which he is a beneficiary, but has contributed to it becoming more and more widespread.”

People’s Daily, the main newspaper of China’s Communist Party, cited “controversial remarks allegedly inciting racial hatred” by Mr. Trump. Taiwan’s government-owned Central News Agency reported that his White House tenure had helped “promote the rationale of white nationalism.”
