Tell that to the last President.
I mean, if you think this is a bad practice, shouldn't we end it now? And if you don't think it is a bad practice, why feign anger at the previous administration?
(If you don't like factcheck.org, fine, but the facts have been widely reported elsewhere as well.)
I don't think that this gives cover to either Obama or Bush for any abuses of the system under their administration, but suddenly changing to a zero tolerance policy and massively widening the scope of family separation counts as a difference, no?
Now, what does that have to do with the point you were replying to?
