German Chancellor Angela Merkel's government is concerned that white supremacists in the United States are being emboldened by the election of Donald Trump.
A video circulating on the internet which showed members of the "alt-right" movement – a grouping that includes neo-Nazis, white nationalists and anti-Semites – meeting on Saturday in Washington a few blocks from the White House.
"I don't think this is Trump's ideology because he seems to be largely free of ideology. But these people are riding on his coattails. We are watching this very closely," an official said.
"One of the greatest mistakes humanity ever made was a failure to recognize the danger of fascism early enough and tackle it head on," said Yair Lapid, a member of the foreign affairs and defense committee in the Israeli Knesset. "We cannot let history repeat itself."
In the video, taken inside the conference and published by The Atlantic, Richard Spencer, a leader of the "alt-right" movement, says America belongs to white people.
