I don't know what you mean. Here's what the LA Times (June 26, 2017) quoted of Rendon:
“Often we fine-tune a bill when it goes from one house to another through the committee process. This was so grotesquely beyond that,” Rendon said in an interview Monday. “This was essentially a $400-billion proposal without a funding source. That's absolutely unprecedented...This was not a bill, this was a statement of principles.”
That's about as clear as it gets. Lara wrote the easiest part of the bill, then punted it to the Assembly to put together the most difficult part, financing. When the Senate Appropriations Chair does that, it's the legislative equivalent of a slap in the face. To put it in perspective, Paul Ryan didn't send his latest "healthcare" bill to the Senate absent financing, did he?
Additionally, there are a whole lot of other issues Rendon has already agreed with his lower house colleagues to consider in the Assembly schedule. What Lara did is basically tell him to ditch the Assembly schedule to spend the rest of the legislative session developing financing language--a huge, politically challenging undertaking--for a bill that 1) his committee had the jurisdiction and responsibility to develop; 2) the Assembly might not have time to pass; and 3) if it did, wouldn't even go into effect if it did pass and was signed by the governor. If you don't know what I mean by 3, just read section 100670(a) of the bill.
That's not the end of it though. Just because a bill is tabled, doesn't mean it can't be brought up for consideration again. I posted a few examples of this a few weeks back from previous healthcare bills. Absolutely nothing is stopping the president of Nurses United and Lara from developing financing language and appealing for reconsideration. Lara is the damn committee chair who is supposed to be doing this. Why isn't he (maybe he is, but I haven't seen anything to indicate it)?
Finally, if the president of Nurses United is so confident, why not skip the horrible sellouts in the Assembly altogether and put the bill on the ballot? She can just drop the Pollin numbers in and see what happens, right? It'd be interesting to see the Legislative Analysts Office analysis of it, that's for sure. Plus, the bill will come through the voters anyway, for popular approval of new taxes, alterations of existing propositions, and/or a ballot measure in opposition to the bill. In truth, I think we both know why she's not doing this and is wasting her time yelling at Rendon.
