WASHINGTON – President-elect Joe Biden’s national security Cabinet may be bare on Day One of his presidency, but an inauguration-eve spurt of Senate confirmation hearings suggests that won’t be the case for long.While the nominees to head the State Department, the Pentagon, Homeland Security and the intelligence community are unlikely to be confirmed by the time Biden takes the oath of office at noon Wednesday, some could be in place within days.The Senate typically confirms some nominees, particularly the secretaries of defense, on Inauguration Day, though raw feelings about President Donald Trump four years ago led to Democratic-caused delays, except for James Mattis at the Pentagon.
