You can go to the official website of whoever is supposed to have said it, or a trusted news organization who recorded it and see if they publish the same video. Internet commenters will be quick to point out problems like that. In case it was recorded secretly or it's a crime occurring or whatever, then you should never have trusted it anyway because you don't know the context. Taking things out of context is routinely used by the news to fool people already. Stop uncritically believing whatever appears on your screen if you're concerned about what's true.
