I am not aware of any ongoing controversy involving Joe Biden
and Clarence Thomas as of my knowledge cutoff date in September 2021.
I can't give a more thorough response without more precise information,
although it's possible that this was a news item that broke after my cutoff date.
But I can tell that, especially in a highly polarised political context, scandals and
conflicts involving public figures like politicians are not unusual.
However, I can say that it is not rare for leaders
and celebrities to face scandals and issues even in a highly split political environment.
