For example, whatever one thinks about US immigration policy (I think it’s utterly broken to the point of absurdity), a cursory attempt to figure out the approximate net number of illegal immigrants added during Biden’s tenure comes suggests that the net change was pretty small. It seems that there has been a trend toward net addition of illegal immigrants in the last few years that (a) is small compared to the total number in the US and (b) started well before the end of the last Trump administration.
I did find plenty of partisan sources trying to shock me with numbers of border encounters that contain many digits, but there doesn’t seem to be much explanation of why this is a useful statistic or to what extent Biden’s administration had much to do with it. (There was a program derisively referred to as “catch and release” that seems likely to have resulted in a temporary increase in “border encounters,” but I don’t see evidence that it had much effect on net illegal immigration.)
As for graft, I genuinely have no idea what you’re referring to.
