Time will tell. I think the answer is yet. I am inclined to avoid naming specific, relatively recent instances, but I think it would be fair to say that we're in a world with very high skepticism of the media and politicians have been taking that into account by claiming that the news is simply lying, that what they're reading is fake, etc.
It cuts both ways. We don't trust the media, and we don't trust the politicians. So when a politician says that the media is lying, we tend to believe whatever we want to believe.
The loss of truth is a serious thing for a society. (Yes, back in the Walter Cronkite days we had less truth than we thought we did. We had more agreed-upon truth that matched reality than we do today, though, and I think the difference matters.)
