I believe this happened at the CPAC conference in early January.
Former Sen. (and current senior campaign adviser) Lauch Faircloth endorsed Dole saying “Only Elizabeth Dole can unite our party, lead us to victory and maintain a conservative Republican voice for North Carolina in the U.S. Senate,” and he said she has the integrity, common sense and strength the state needs.
Sen. Helms (at CPAC in February) said, "She'll make North Carolina proud when she walks down the center aisle in the Senate next fall.... [I introduce to you] [t]he [next] new conservative Republican senator from North Carolina, Elizabeth Dole."
