Fair enough. 30 bills.  Let's run through some of them:  
 - 13 of them are reversals of recently enacted regulations.  That's hardly 'legislation'.  
 - three bills appointing people to the board of the Smithsonian; 
 - name a VA clinic in Pago Pago, Samoa; 
 - name a VA clinic in Pennsylvania the Abie Abraham Clinic; 
 - H.R. 255: Promoting Women in Entrepreneurship Act
 - S. 305: Vietnam War Veterans Recognition Act of 2017
 - H.R. 72: GAO Access and Oversight Act of 2017
All of the rest of are similarly obscure and were created well before Trump's inauguration.
Frankly, I can't find any legislation that he championed that even remotely relates to his campaign promises.  
You can put lipstick on it, but it's still a pig.
