I don't even know why someone would say something as uncalled for as this, to be honest. Usually, I don't even see the first lady on the news, so I am not sure either whether this is about some rumor which is circulating among the people who is likely to vote for Trump.
It is either a rumor which has started to circulate on the internet about Jill Biden or someone thought it would be funny to create some deep fake pornography of the women within the Biden family, for whatever reason.

Regardless of the reason, it is kind of disturbing someone would lash out like this here in the forum without giving further context...
