Chris Christie expressed a similar view during the first Republican primary debate:
Moderator: Another issue that is related to this is that almost seven million migrants have crossed this border, our southern border, during the Biden administration. Governor Christie, what would you do about the seven million who are here? How would you handle them? What would you do?
Christie: Look, Martha, the first thing we need to do is to stop any more from coming. That’s the first thing we need to do. Then, the next thing we need to do with the folks that are here is to, again, as we’ve talked about all night tonight, we have to have law and order in this country. We have to enforce the law. What that means is to make sure that people who come here illegally are not rewarded for being here illegally.
We have so many wonderful people from around the world who are waiting
in line, following the law to try to come here and pursue the American
dream, and those people are waiting and waiting and waiting because we
haven’t dealt with the problem of the folks who are here. We have to
have them detained. We have to make sure that they are not rewarded
for having broken the law.

Moderator: I just want to clarify, would you send those people back?
Christie: Of course, you'd have to.
Additionally, Vivek Ramaswamy mentioned in a speech that he would "deport universally", because "we are a nation of laws", and would only support a pathway to legalization for illegal migrants who came to US through no fault of their own.
