AUSTIN, TEXAS - A national tea party group will endorse Ted Cruz for the U.S. Senate.
Political operatives with knowledge of the endorsement say the Tea Party Express will make the announcement in Irving onWednesday.
The officials asked not to be named because they were not authorized to pre-empt Wednesday's announcement.
Cruz has fought hard to win tea party and conservative endorsements while running against his chief rival, Lt. Gov. David Dewhurst.
Cruz has called Dewhurst a timid moderate while receiving support from groups such as FreedomWorks and the Club for Growth.
Dewhurst says he is the proven conservative and has won the endorsement of former Arkansas Gov. Mike Huckabee and numerous Texas Republican organizations.
Officials for the Tea Party Express and the Cruz campaign declined to confirm or deny the endorsement.
