How does the Democratic Party deal with the Venezuelan gang activity in Aurora

I understand it may all be propaganda but the videos of Venezuelan gangs commandeering apartment complexes are quite compelling. I believe the border is a big issue moving into the elections. What is the argument moving forward? Are these issue due to Trump administration failures, are the stories extremely exaggerated or not real at all, or the Americans experiencing these issues are negligible and in the grand scheme of things are worth it to give a better opportunity to those seeking asylum?
