Trump has been president for four years. At some point the chief officer is accountable for the people beneath him, particularly the people he chose and the people chosen by the people he chose.
I want Trump inaugurated on Jan 20, but if it doesn’t happen he shares a good part of the blame for not doing more to clean out DOJ and FBI. The top people in both are his appointees, as is every US attorney from coast to coast.
Trump has done many amazing things, especially while being under continuous virulent attack and having no stable of political cronies to fill the many government positions. Did you provide your list of competent candidates when he took office? He has done an amazing job with all the Democrats and ~half of the Republicans in opposition.
