The joint appearance combined a corporate investment announcement with a political campaign event. Both Tagesschau and Handelsblatt reported the appearance and the announcement of a new Audi facility in the US, but the available reporting does not establish further details about the project.
Handelsblatt reported that Christiane Benner, head of the IG Metall union, called Döllner’s appearance unacceptable and described it as highly embarrassing. Her criticism places the focus on the decision by Audi’s chief executive to appear on the campaign stage with Trump.
Tagesschau reported that Audi’s own corporate guidelines could become relevant in connection with the appearance. The available sources present this as a possible issue, not as a confirmed breach of company rules.
