Yes, sometimes the media can say something that's not true. But this example was immediately pointed out by, guess who, the rest of the media. And it was a kind of weird thing to be wrong about too, so it seems more likely that the speaker genuinely believed they were telling the truth as opposed to being dishonest (I mean, who does it benefit to be dishonest about that? Nobody). Though that doesn't excuse the fact that they really should have double-checked that before saying it. They absolutely were wrong, and they absolutely deserved to be called out by everyone else.

But even if they were dishonest that one time, one example, no matter how widely-reported, indicates systemic dishonesty.
