Originally, the captain announced we might divert into Knoxville but were told they did not have functioing customs/immigration.
However, if someone deplanes and goes through customs and immigration, I don't think they can then be permitted to reboard if doing so means mixing in with passengers who have not been processed by CBP. So AFAIK either the entire flight would need to do CBP or no one who deplaned could be permitted to reboard.
