I've been away from computer and I saw you already responded to mix up but I found something else. Biden had a son named Hunter.  Kerry is stepfather to Chris Heinz.    I had not read Hunter Biden's bio but this just caught my attention:>  (Hunter) Biden was appointed by Bill Clinton to serve in the United States Department of Commerce[7] under Secretaries Norman Mineta and William M. Daley.  William M. Daley, brother of Richard M. Daley (see Q 1947) was in the news not so long ago https://chicago.suntimes.com/news/rahm-emanuel-richard-daley-tensions-bill-daley/
