He's got nothing.  This is a desperate attempt to claim that he actually accomplished something in his first 100 days, which ends in 8 days: "See?  I revealed my MASSIVE tax cut plan!"
This isn't driven by governance, it's driven by his obsession with how he's covered in the press.  100 days is an arbitrary deadline, but it's always mentioned as a milestone in the press so he feels he needs to get a positive grade.  He'll do anything to get positive press coverage.  That's what's truly frightening.
