German politicians are calling for Donald Trump’s ambassador to Berlin to be expelled after he was accused of meddling in domestic politics. Richard Grenell caused outrage over the weekend when he told right-wing outlet Breitbart that he wanted to “empower other conservatives throughout Europe.” Martin Schulz, former leader of the Social Democratic Party, said: “What this man is doing is unheard of in international diplomacy. If a German ambassador were to say in Washington that he is there to boost the Democrats, he would have been kicked out immediately.” The leader of left-wing party Linke, Sahra Wagenknecht, said Berlin should immediately get rid of Grenell. “Someone like U.S. Ambassador Richard Grenell, who thinks he can lord over Europe and determine who is governing here, he can no longer stay in Germany as a diplomat,” she said. Germany’s foreign ministry is seeking clarification from Grenell about his comments. A meeting is scheduled for Wednesday between him and State Secretary Andreas Michaelis.
