GOP field grows: Fiorina, Carson to launch presidential bids

Former technology executive Carly Fiorina and retired neurosurgeon Ben Carson are set to launch their runs for president.

Fiorina is likely to be the only prominent woman to seek the GOP nomination, with Carson the only likely African-American. They are both also political outsiders in a field likely to be dominated by governors, former governors and senators.

The two are not considered political allies and the timing of their Monday announcements is coincidental.

The 63-year-old Carson is scheduled to make his formal announcement in a speech from his native Detroit shortly after having breakfast at a local museum of African-American history.

The 60-year-old Fiorina will enter the race with a video posted online.
