In the United States today, it seems all politics has become entirely situational, and Republicans have put party over civility. Had Ben been attacked by a Democrat, many on the right who are refusing to believe the assault occurred — or outright praising it — would be hailing him as a victim of liberal rage. Had Hillary Clinton’s campaign manager, rather than Mr. Trump’s, grabbed my arm, I would not have been abandoned by many of my friends and mentors at Fox News, or my employer, Breitbart News. But I was inconvenient to their political narrative.

Will Republican politicians condemn Mr. Gianforte? If not, we’ll have many more people to blame for the delegitimization of the press than President Trump.
