The bill is not reference by number nor is it linked. What bill is it and what proof is there of the "tighten enrollment" for precheck?

Several bills have been proposed to rein in "TSA ... handing out PreCheck status like Halloween candy" (Assistant Federal Security Director Rebecca Reoring). The DHS Inspector has requested that Congress pass these types of bills. These bills would end "Managed Inclusion" programs.
