New Pentagon chief racing to make changes before Trump's exit

Acting Defense Secretary Chris Miller has just 63 days to put his stamp on the Pentagon.

Miller, a former Green Beret and counterterrorism professional, has been unexpectedly vaulted from midlevel National Security Council desk officer to Pentagon chief in under a year. Now, Miller is looking to use his position to make quick policy changes that incoming President Joe Biden is unlikely to overturn before the clock runs out on the Trump administration in late January.
