A tweet by Donald Trump’s campaign "Trump War Room" and shared thousands of times shows a video clip of Joe Biden calling the US president’s supporters the “dregs of society.” However, this video was edited to deceive. If you view the full speech, Biden quip about the "dregs of society" was a condemnation against those that discriminate against the LGBTQ community.
As reported by AFP Fact Check...
The remark -- had Biden been hitting out at people for supporting the president -- would have been similar to 2016 Democratic candidate Hillary Clinton saying half of Trump’s backers could be put “into what I call the basket of deplorables,” a comment that hurt her in the election run-in.
But Biden’s full remarks at a September 2018 Human Rights Campaign dinner make clear he was opposing discrimination rather than people's broader political leanings.
