When I've wanted it to not do things like this, I've had good luck directing it to... not look at those sources.

For example when I've wanted to understand an unfolding story better than the news, I've told it to ignore the media and go only to original sources (e.g. speech transcripts, material written by the people involved, etc.)

Deep Search is pretty good for current news stories. I've had it analyze some legal developments in a European nation recently and it gave me a great overview.

That use case seems pretty self defeating when a good news source will usually try to at least validate first-party materials which an llm cannot do.
