When Biden dropped out of the race his cabinet put out statements. SecDef listed what he thought Biden did as President and then as CiC.
Notice as CiC the only thing of substance written was he signed funding (NDAA) for them.
The current NDAA has been sitting on his desk for 4 days already and he hasn't signed it. He signed the funding bill yesterday but didn't find it important enough to sign the NDAA.
The only significant act as CiC Austin credits Biden for hasn't been done.
