Can you tell me about the political issues surrounding the US border security in recent years?

I think the general problem is that over the last few years the US has not made the border with Mexico as secure as it once was. Even though we are separated by a large ocean from other countries, it is actually easier for foreigners to get into the US now than ever. In fact, there have been many reports about an enormous increase in the number of Central American children who are crossing into the US unaccompanied.
