Both of those sources are just bullshit propaganda. There are no 'open borders'. You're just being manipulated.
They also are really poor about citing evidence for their claims. The best thing they've got is a vague '124 percent more' with no real figures, and 'some states have pushed boundaries'.
If they want to tighten policy around what qualifies as emergency care then be my guest. The rest of this is just pushing a bullshit narrative.
