Have I misunderstood?
I thought crew Dragon was ready and that it was the ongoing NASA testing that is the only thing stopping it from launching sooner?
Also, given that NASA apparently failed to organise a fixed cost contract with Boeing for initial copies of their capsule, which is now costing billions more of taxpayers money than was originally estimated , and that SpaceX has delivered on cheaper costs to loft payloads to LEO, thereby driving launch costs generally down, it was indeed a very cheap shot at SpaceX by Mr Bridenstine.
Personally, I'm not a great fan of Elon personally, and I do wish his presentation skills were better (I found the recent presentation about Starship dull; Scott Manley's summary is far better, IMO https://www.youtube.com/watch?v=wRF41f7hPWE - but with SpaceX I think he's doing a great job. I also look forward to seeing Blue Origin getting stuff into orbit too!
