Agreed.  Unfortunately,  Callista is etched in history as the congressional aide cavorting with Newt (at the time married to his second wife) while he led the charge against Bill Clinton for lying about his own unsavory affair with a White House intern... both political parties were up to their necks in sleaze and lies at the time.   Yes,  the optics are in-your-face insulting under the circumstances...  and no,  she is not qualified in any sense to function as an ambassador to the Holy See.  This appointment is typical of Trump's m.o. across the board... insulting his perceived enemies.
