Presidential Primaries

Three more names are about to be added to the already crowded 2016 Republican presidential field. Dr. Ben Carson announced his intention to make a run at the Presidency today, and announcements from both former Arkansas Governor and 2008 Presidential candidate Mike Huckabee as well as former Hewlett Packard CEO Carly Fiorina expected to be forthcoming. These additions will bring the number of announced GOP candidates to six, including three sitting U.S. Senators. Chief Fox News Congressional correspondent Mike Emanuel has more from Washington.
