Typical career politician response:   "Guns kill more than 33,000 Americans each year"  No humans were involved, obviously. 
With regards to the suggestions you posted:
1.  Why were bump stocks ever made legal in the first place?  Please ask some of your buddies in the Obama administration and let us know.  (We all know the finger pointing that would be going on if an item like that was approved under any other administration). 
2.  Reinstate a ban on military-style assault weapons?  Are you talking about reinstating the Clinton era ban?  The "ban"  that did nothing to change the functionality of the weapons? 
3.  How much money do you propose get thrown into this research?  Do you want to fund research for stabbing deaths as well, since there are more of those every year? 
4.   Strengthen background checks?  What do you propose?   Did the Vegas shooter fail a background check? A delayed response does not mean you are denied.  Please clarify this.
