U.S. Vice President JD Vance's office says he met the leader of a German far-right party during a trip to Germany on a day he gave a speech castigating European leaders.

The vice president delivered a scolding speech advocating that Europe move over to accommodate the rising anti-migration, nationalist voices they have sought to block from power.

In an interview with Deutschlandfunk radio due to be broadcast on Sunday, Chancellor Olaf Scholz criticized Vance's remarks as highly unusual, adding that Germany had a firewall against extreme right-wing parties for a good reason, citing Germany's past under National Socialism.
