Besides which: Dem Reps go with their constituents to *try* to examine an ICE facility, as is their right and job. I don't think Baraka or Iver were *planning* to get knocked about and arrested. Others have tried, mostly w/out success, and thus with far less fanfare.
It seems to me that it's quite a lot to ask that people not only do the jobs they're paid for, are *ethically* required to do, and also have to manage PR for themselves because the press is too busy covering Trump as though he were somehow normal. Should they anyway? Sure; if they can.
Not everyone has a great talent for capturing a feckless press, going uphill. Newsom's quite good at it; unfortunately, he's also a scumbag, mostly. You pays your money and you takes your chance.
