Aren’t they following the US Constitution? Doesn’t the Federal government have the power to protect the borders?
Power, yes. Desire, inclination, motivation, NO!
The case involved the issuing of new enforcement guidelines by the Department of Homeland Security. After initially attempting to impose a 30-day moratorium on all ICE deportations, the department issued guidance that restricted ICE agents to targeting three types of illegal immigrants for arrest and deportation: recent border crossers; threats to public safety; and national security threats.
What does “recent border crossers” even mean ? It looks to me like the vast majority are walking across, getting their papers and being bused out never to be seen or heard from again.
