If McConnell meets with Newt and explains what the Senate can do in 100 days and why the rest is not on the first 100 day list, I would be okay with that if Newt is. Do what is possible in that first time window. Then push for a second 100 days on the rest of the agenda. If McConnell is being his RINO establishment self, then it's time for him to find a new position in the Senate.
I interpreted McConnel’s remark as “not on the agenda at all” and not “not in the first 100 days”. I hope you are right.
