I don't know or particularly care what his involvement was on the drafting of that bill. I do know that his statements after the fact reflect that felt that the bill was essentially the only way to get the ball rolling on beginning to get changes in.
I reject that approach, as the other G.O.P. senators clearly did. The bill would have basically codified into law the huge flow of unchecked immigration from our southern border that began when the Biden administration took office. I reject the idea that we should throw money or resources at a problem without enforcing existing laws first. And as for the flow that this bill would have willfully enabled, forget it. It was unacceptable, and the idea that we should use that as a "starting point" is silly.
