Sioux City, Iowa (CNN) - Mitt Romney's presidential campaign moved quickly Friday to capitalize on a high-profile endorsement from South Carolina Gov. Nikki Haley by sending out a wave of robocalls across the early primary state that feature Haley herself making the case for the former Massachusetts governor.
"Hi, this is Gov. Nikki Haley, and this morning I announced my endorsement of Mitt Romney for President of the United States," Haley says in the call, which was received by a Republican voter in Rock Hill who provided it to CNN.

In the one-minute call, Haley draws an implicit contrast with the Republican frontrunner, former House Speaker Newt Gingrich, whose ascent in the polls has come at Romney's expense in several key early voting states.
Without naming him, Haley casts Gingrich as a creature of Washington.
"Mitt Romney knows what it means to make decisions, real decisions, not simply cast a vote," Haley says in the call. "He is not a creature of Washington. He knows how the private economy works, how to fix it, and most importantly how to solve problems. And he has proven it."
At the end of the call, Haley invites people to attend a rally with her and Romney on Friday in Greenville.
The calls are being paid for by Romney's campaign.
