Hunting with the Trumps

All week I have been hearing about the whole Trump sons hunting thing and I couldn't help but wonder if the outrage would be just as great if the animals that were killed were deer or something else that normally gets hunted in the US. Now, I don't know if what they were doing was illegal, I would've checked but I am afraid that I would see those pictures again and I am not interested in that in the least, but from the coverage it does not seem like it was illegal. So why the big deal? Don't get me wrong, I am no fan of the Trump family inc. at all but why are people more outraged by dead animals in Africa but not the ones in the US? Now if it is in fact illegal then obviously they should be held responsible.
