Wolfeboro, New Hampshire - Republican US presidential candidate Mitt Romney's most bitter rival for his party's nomination has agreed to speak at the nominating convention in Tampa, Florida, later this month.
Rick Santorum, the former presidential candidate who lobbed harsh criticism at Romney during some bitter primary contests, will join a host of other big-name Republicans as headline speakers, according to Republican sources.
Former Florida Governor Jeb Bush will also speak at the convention, along with Oklahoma Governor Mary Fallin and Tea Party hero and Senator Rand Paul of Kentucky.
Paul spent much of the year campaigning against Romney on behalf of his father, Texas Congressman Ron Paul.
Details about when the speakers will take the stage have not been released.
