U.S. President Donald Trump’s criticism of journalists amounts to an attack on the freedom of the press and could provoke violence against reporters, the UN’s human rights chief said on Wednesday.

Zeid Ra’ad al-Hussein said Mr. Trump had also made worrying remarks about women, Mexicans and Muslims and went on to question the President’s approach to immigration and decision to pardon former Arizona lawman Joe Arpaio.

“It’s really quite amazing when you think that freedom of the press, not only sort of a cornerstone of the U.S. Constitution but very much something that the United States defended over the years is now itself under attack from the President,” the UN High Commissioner for Human Rights said.

“It’s sort of a stunning turnaround. And ultimately the sequence is a dangerous one,” he told a news conference in Geneva.
