It appears to be Trade Gothic:

If you don't own it and don't want to buy it, I believe there is a free Google font that is a spot-on match, called News Cycle.

Thanks for posting this cover. While some people may find it too simple, I think it is refreshingly understated and direct.

Excellent, thank you...I've always loved this cover and last night decided to see what else the designer, Rodrigo Corral has done. Boy, was I blown away by the amount of work I own of his and never knew, and great work at that. Thanks again.

Thank you for crediting the designer. I've bookmarked his website, and will be checking out his other work.
