One of my favourite news sites is Newsy.com. It's not specifically designed for learners of English, but the transcripts and on-screen extracts from source articles make the short video reports much more accessible than they would otherwise be. The videos are organized into categories (World, US, Politics, Business ...), so you can easily find something of interest. However, the beautifully-designed Newsy app is something else again. It works brilliantly on the iPad—and it's free! What are you waiting for?
