What are the most popular Spanish-language national newspapers with a primarily U.S. focus?

I just graduated from high school and I’m looking for ways to maintain my Spanish aptitude. I’m looking for the most popular Spanish-language national newspapers with a primarily U.S. focus. We read a bunch in class, but I can only remember one, El Mundo, which has a focus on Spain.

Any suggestions? I’m sure that I’ll recognize the names once I see them.
