President-elect Joe Biden is on track to take office without key Cabinet members being confirmed on the day of his inauguration, a result of the Republican-led Senate moving much more slowly to schedule confirmation hearings and votes than it has for previous presidents. “There’s never been a more important time to get confirmed nominees in place because we’re dealing with an economic crisis, a health crisis and a political crisis,” said David Marchick, the director of the non-profit Center for Presidential Transition at the Partnership for Public Service.
