Well he does know that it includes funding for the wars in the Middle East and Ukraine. He does know that it includes immigration reforms/funding. He has commented that it is being "negotiated" in private amongst "the Firm". It is then being rushed for a vote without ample time for review/comments/debate/amendments. So you think he should vote on it without knowing what's in it or what? Or keep quiet about the process?
As far as I know he hasn't made a decision (vote) yet but is complaining about how this bill is being handled. Because the way the bill is being handled he is inclined to not support it.
You really think it's going to be a good bill based on the subjects it covers and who is drafting it and then pushing it without ample review?
