You are correct, Bush League Republicans are just as responsible for these deaths as any Democrat.
Flake, Corker, Hatch, Heller, Alexander, Graham, McCain, Murkowsky, Hoeven and Rubio all voted to give them amnesty and make them citizens.
Martinez-Gonzalez was killed last year by a DACA dude. She didn't get much press. She was killed in October. That's 10 months into the Trump era. He didn't end daca until September of last year. .Gov doesn't care.
