Background: I'm a full time photojournalist on staff at a daily newspaper.
As others have said, my personal recommendation is either Canon or Nikon. If you plan this as a long term career it is better to start putting your money into a system that will last. Both Canon and Nikon offer the widest range of lenses/accessories and have professional support systems (CPS and NPS). As a photojournalist, the colleagues you'll run into on assignments or on the sidelines will be shooting Canon or Nikon so if you need to borrow a battery or lens it will be that much easier. Chances are the majority of your classmates will also be using one of these two so you'll get this sharing experience right away.
Now some advice you didn't ask for: I get asked for major advice by high school students interested in photography fairly often. These days my usual recommendation is to get a degree in something other then photography. In the long run I think most will benefit much more from having a degree in business, accounting or marketing with a only minor in photography.
Unfortunately most working photojournalists (and photographers in general) these days are self employed small business owners. The number of photogs with staff jobs is shrinking on a monthly basis. As such not only will you have to know how to be a photographer, you'll also need to know how to run a business. Pay the bills, keep the books, market yourself to get and keep clients. I would imagine this applies to many graphic designers as well.
Now obviously these topics won't be near as much fun for someone with a desire to capture the moment. I can understand it would be a huge decision to spend most of your college focusing on these topics instead of what you have a passion to do. If nothing else please consider at least getting a minor in a discipline unrelated to the creative arts. There are hundreds of students graduating with PJ degrees each year for only a handful of jobs. I've seen amazing photographers struggle to pay the bills every month because they don't know how to run a business while mediocre photographers with greet business/networking skills rake in the dough.
Trust me, I'm not trying to discourage you at all. Photojournalism is a fun and rewarding profession and everyone should always follow their dreams. If you aren't happy what's the point right? I just wanted to mention this because from talking with college students these days it seems like there is very little real world advice about the state of the industry and job market being taught.
Feel free to PM me if I can ever be of any help in the future.
