Nobody cared until Trump got them to sign a safe harbor agreement where both sides agreed that an asylum seeker has to apply for asylum in the first country they pass through, meaning a shitload of "asylum seekers" crossing illegally into the US would have to instead apply for asylum in Guatamala.
Well as you can see this pissed off Democrats because they have decided we are the world's hospital and piggy bank, so they are now in Guatamala trying to get politicians elected who are going to overturn Trump's agreement.
Sure, they claim they are there for other reasons, because suddenly going to Guatamala 3 days before their elections is very important.
