Pawlenty visited with Haley Wednesday.
Haley's endorsement in the first GOP contest in the South would be a prize for any presidential campaign. Pawlenty called it a courtesy visit.
Pawlenty said his decision on a bid for the White House will come within about a month, and the party is looking for someone to take the country in a new direction.
The two-term governor last visited the state in June for GOP fundraising events. His Wednesday visit included a stop at an Aiken County Republican group's meeting.
