Mmm; I guess it isn't a direct face eat (but my brain sort of made the assumption as he's a conservative commentator and has been pushing how Trump's policies would be good for American citizens).

Basically, he's been talking about immigrants have been taking jobs (and, apparently, actually believes that the immigrants Trump have been deporting have mostly been dangerous) and, now, is suddenly surprised that citizens like himself are getting deported, as if the xenophobia and cruelty-is-the-point of the trump administration wouldn't fall back on U. S. citizens (or, perhaps more accurately, as if the administration would care if it did).

But, yeah, you bring up a good point that it isn't a direct face eating.

They are acknowledging that the deporting of 'violent illegal immigrants' is actually leading to citizens being rounded up. Their face isn't being eaten directly, but the thing they wanted is backfiring in general.
