Rounding up its first week of broadcasting, Al Jazeera America has also appointed a flurry of national bureau correspondents. First up is Libby Casey, who will be their Washington correspondent based in D.C. You may know her from her past work with C-SPAN and Alaska Public Radio. "Go get 'em, @libcasey," cheered John Harwood of The New York Times and CNBC. Casey replied to fans, "Thanks so much! & Thanks for checking out @ajam!"
