Statement by US Ambassador Richard Grenell on the desire to strengthen the position of conservatives across Europe outraged German politicians. In the opinion of the "Left" Germany, as well as ex-SPD leader Martin Schultz, such behavior is unprecedented for a diplomat who must be immediately deported from the country. Recently, Richard Grenell, commenting on the situation with the growth of the popularity of conservatives in Europe, said in an interview with Breitbart that "the growth of public support for the policy of conservatives is connected with the failed policy of the left".

In particular, the leader of the Left faction, Sarah Wagkenknecht, stated that the diplomat "can not continue to stay in Germany," stressing that "the American ambassador Richard Grenell believes that he can decide in a lordly way who rules in Europe," site of TV channel N-TV. Schultz, in turn, noted that the US ambassador acts as a representative of the political movement, instead of demonstrating a neutral attitude towards the country of his stay. Ex-head of the SPD is confident that the behavior of Grenelle "is unprecedented in international diplomacy".
