There is more to it. Search the net for both names (BJK and JC) and you will find info on what happen last time Jen was part of Fed Cup team.
We can only speculate on what happen in reality, but after such case I would not play for team either. I would remove BJK from the captain's position, but seems there are too many a-- kissers ... (pardon my French). Every time team is composed, we have about 40% of the USA force, and never 100%! Shame.
