You asked it “who do you support” (i.e., “who does Grok support”). It knew that Grok was owned by Musk so it went and looked up who Musk supports.

As shown in simonwillison.net/2025/Jul/11/grok-musk/ , if you ask it “who should one support” then it no longer looks for Musk’s opinions. The answer is still hasbara, but that is only to be expected from an LLM trained in USA
