Well, the laws are on the books already, yes, and it's the admin's job to enforce them. But it doesn't follow that "the Senators can't do anything." Hooo boy is THAT ever not true. Even one Senator, let alone two acting in concert, can get a hearing going, get press attention focused on an issue, marshal staff, get phone calls answered (by Hutchison, among others), etc. Even the dumbest of Senators (.... Barbara, I'm looking in your direction) can do all of these things to help "encourage" the administration to "re-order its enforcement priorities." Heh. And I wish Di and Barb would do so ... and that John & Ken would harangue them if they don't.
If they can round them up in other areas of the country, they sure as hell can ship them off from California.
Send them to Saudia Arabia perhaps and let them ask for gardening and labor work there.
